The DSI-HDMI converter, ADV7535, driver uses four i2c memory maps: MAIN,
DSI-CEC, EDID and PACKET.
While the MAIN address is hard-coded in the ROM chip, the other three
can be programmed into the MAIN memory map.
Currently, the three memory maps addresses, that can be programmed, are
hard-coded into the code.
In order to avoid conflicts with other i2c clients on the bus, update
the driver to use configurable addresses specified in DTS file.

It's pretty common that on some reference design or validation boards,
one pin could be used by two devices on board, and the pin route is
controlled by a GPIO. So to assert the pin for given device, not only
the pinmux controller in SoC needs to be set up properly but also the
GPIO needs to be pulled up/down.
The patch adds support of a device tree property "pinctrl-assert-gpios"
under client device node. It plays pretty much like a board level pin
multiplexer, and steers the pin route by controlling the GPIOs. When
client device has the property represent in its node, pinctrl device
tree mapping function will firstly pull up/down the GPIOs to assert the
pins for the device at board level.

RPMB. This CMD23 for RPMB need to set the bit 31 to its argument, if not, the
RPMB write operation will return general fail.
According to the sdhci logic, SDMA mode will disable the ACMD23, and only in
ADMA mode, it will chose to use ACMD23 if the host support. But according to
debug, and confirm with IC, the imx6qpdl/imx6sx/imx6sl/imx7d do not support
the ACMD23 feature completely. These SoCs only use the 16 bit block count of
the register 0x4 (BLOCK_ATT) as the CMD23's argument in ACMD23 mode, which
means it will ignore the upper 16 bit of the CMD23's argument. This will block
the reliable write operation in RPMB, because RPMB reliable write need to set
the bit31 of the CMD23's argument. This is the hardware limitation. Due to
imx6sl use SDMA, so for imx6qpdl/imx6sx/imx7d, it need to broke the ACMD23 for
eMMC, SD card do not has this limitation, because SD card do not support reliable
write.

Pull x86 TSX Async Abort and iTLB Multihit mitigations from Thomas Gleixner:
"The performance deterioration departement is not proud at all of
presenting the seventh installment of speculation mitigations and
hardware misfeature workarounds:
1) TSX Async Abort (TAA) - 'The Annoying Affair'
TAA is a hardware vulnerability that allows unprivileged
speculative access to data which is available in various CPU
internal buffers by using asynchronous aborts within an Intel TSX
transactional region.
The mitigation depends on a microcode update providing a new MSR
which allows to disable TSX in the CPU. CPUs which have no
microcode update can be mitigated by disabling TSX in the BIOS if
the BIOS provides a tunable.
Newer CPUs will have a bit set which indicates that the CPU is not
vulnerable, but the MSR to disable TSX will be available
nevertheless as it is an architected MSR. That means the kernel
provides the ability to disable TSX on the kernel command line,
which is useful as TSX is a truly useful mechanism to accelerate
side channel attacks of all sorts.
2) iITLB Multihit (NX) - 'No eXcuses'
iTLB Multihit is an erratum where some Intel processors may incur
a machine check error, possibly resulting in an unrecoverable CPU
lockup, when an instruction fetch hits multiple entries in the
instruction TLB. This can occur when the page size is changed
along with either the physical address or cache type. A malicious
guest running on a virtualized system can exploit this erratum to
perform a denial of service attack.
The workaround is that KVM marks huge pages in the extended page
tables as not executable (NX). If the guest attempts to execute in
such a page, the page is broken down into 4k pages which are
marked executable. The workaround comes with a mechanism to
recover these shattered huge pages over time.
Both issues come with full documentation in the hardware
vulnerabilities section of the Linux kernel user's and administrator's
guide.
Thanks to all patch authors and reviewers who had the extraordinary
priviledge to be exposed to this nuisance.
Special thanks to Borislav Petkov for polishing the final TAA patch
set and to Paolo Bonzini for shepherding the KVM iTLB workarounds and
providing also the backports to stable kernels for those!"

The page table pages corresponding to broken down large pages are zapped in
FIFO order, so that the large page can potentially be recovered, if it is
not longer being used for execution. This removes the performance penalty
for walking deeper EPT page tables.
By default, one large page will last about one hour once the guest
reaches a steady state.

With some Intel processors, putting the same virtual address in the TLB
as both a 4 KiB and 2 MiB page can confuse the instruction fetch unit
and cause the processor to issue a machine check resulting in a CPU lockup.
Unfortunately when EPT page tables use huge pages, it is possible for a
malicious guest to cause this situation.
Add a knob to mark huge pages as non-executable. When the nx_huge_pages
parameter is enabled (and we are using EPT), all huge pages are marked as
NX. If the guest attempts to execute in one of those pages, the page is
broken down into 4K pages, which are then marked executable.
This is not an issue for shadow paging (except nested EPT), because then
the host is in control of TLB flushes and the problematic situation cannot
happen. With nested EPT, again the nested guest can cause problems shadow
and direct EPT is treated in the same way.

Some processors may incur a machine check error possibly resulting in an
unrecoverable CPU lockup when an instruction fetch encounters a TLB
multi-hit in the instruction TLB. This can occur when the page size is
changed along with either the physical address or cache type. The relevant
erratum can be found here:
https://bugzilla.kernel.org/show_bug.cgi?id=205195
There are other processors affected for which the erratum does not fully
disclose the impact.
This issue affects both bare-metal x86 page tables and EPT.
It can be mitigated by either eliminating the use of large pages or by
using careful TLB invalidations when changing the page size in the page
tables.
Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in
MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which
are mitigated against this issue.

Intel Wired LAN Driver Updates 2019-11-01
This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.
Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine. So change the read error into a
warn while the device is still present.
Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it. So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.
I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.
Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.
Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.
Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
it twice.
v2: Fixed alignment issue in patch 3 of the series based on community
feedback.

Pull arm64 fixes from Will Deacon:
"These are almost exclusively related to CPU errata in CPUs from
Broadcom and Qualcomm where the workarounds were either not being
enabled when they should have been or enabled when they shouldn't have
been.
The only "interesting" fix is ensuring that writeable, shared mappings
are initially mapped as clean since we inadvertently broke the logic
back in v4.14 and then noticed the problem via code inspection the
other day.
The only critical issue we have outstanding is a sporadic NULL
dereference in the scheduler, which doesn't appear to be
arm64-specific and PeterZ is tearing his hair out over it at the

SOMAXCONN is /proc/sys/net/core/somaxconn default value.
It has been defined as 128 more than 20 years ago.
Since it caps the listen() backlog values, the very small value has
caused numerous problems over the years, and many people had
to raise it on their hosts after beeing hit by problems.
Google has been using 1024 for at least 15 years, and we increased
this to 4096 after TCP listener rework has been completed, more than
4 years ago. We got no complain of this change breaking any
legacy application.
Many applications indeed setup a TCP listener with listen(fd, -1);
meaning they let the system select the backlog.
Raising SOMAXCONN lowers chance of the port being unavailable under
even small SYNFLOOD attack, and reduces possibilities of side channel
vulnerabilities.

Add a kernel cmdline parameter "tsx" to control the Transactional
Synchronization Extensions (TSX) feature. On CPUs that support TSX
control, use "tsx=on|off" to enable or disable TSX. Not specifying this

TSX may be used as a part of a speculative side channel attack.

"There are a few core fixes here around error handling and handling if
suspend mode configuration and some driver specific fixes here but the
most important change is the fix to the fixed-regulator DT schema
conversion introduced during the last merge window.
That fixes one of the last two errors preventing successful execution
of "make dt_binding_check" which will be enormously helpful for DT
schema development"

Rename SD3 functions and groups to EMMC to better reflect their intended
use before the binding escapes too far into the wild. Also clean up the
SD3 pin groups to eliminate some silliness that slipped through the
cracks (SD3DAT[4-7]) by unifying them into three new groups: EMMCG1,
EMMCG4 and EMMCG8 for 1, 4 and 8-bit data buses respectively.

Commit 8974558f49 ("mm, page_owner, debug_pagealloc: save and dump
freeing stack trace") enhanced page_owner to also store freeing stack
trace, when debug_pagealloc is also enabled. KASAN would also like to
do this [1] to improve error reports to debug e.g. UAF issues.
Kirill has suggested that the freeing stack trace saving should be also
possible to be enabled separately from KASAN or debug_pagealloc, i.e.
with an extra boot option. Qian argued that we have enough options
already, and avoiding the extra overhead is not worth the complications
in the case of a debugging option. Kirill noted that the extra stack
handle in struct page_owner requires 0.1% of memory.
This patch therefore enables free stack saving whenever page_owner is
enabled, regardless of whether debug_pagealloc or KASAN is also enabled.
KASAN kernels booted with page_owner=on will thus benefit from the
improved error reports.

The bulk of the fixes are dealing with a bunch of issues with the
build system from the compat vDSO, which unfortunately led to some
significant Makefile rework to manage the horrible combinations of
toolchains that we can end up needing to drive simultaneously.
We came close to disabling the thing entirely, but Vincenzo was quick
to spin up some patches and I ended up picking up most of the bits
that were left [*]. Future work will look at disentangling the header
files properly.
Other than that, we have some important fixes all over, including one
papering over the miscompilation fallout from forcing
CONFIG_OPTIMIZE_INLINING=y, which I'm still unhappy about. Harumph.
We've still got a couple of open issues, so I'm expecting to have some

This Kselftest update for Linux 5.4-rc3 consists fixes for existing
tests and the framework. Cristian Marussi's patches add ability to
skip targets (tests) and exclude tests that didn't build from run-list.
These patches improve the Kselftest results. Ability to skip targets
helps avoid running tests that aren't supported in certain environments.
As an example, bpf tests from mainline aren't supported on stable kernels
and have dependency on bleeding edge llvm. Being able to skip bpf on
systems that can't meet this llvm dependency will be helpful.
Kselftest can be built and installed from the main Makefile. This change
help simplify Kselftest use-cases which addresses request from users.
Kees Cook added per test timeout support to limit individual test run-time.

In most configurations, kmalloc() happens to return naturally aligned
(i.e. aligned to the block size itself) blocks for power of two sizes.
That means some kmalloc() users might unknowingly rely on that
alignment, until stuff breaks when the kernel is built with e.g.
CONFIG_SLUB_DEBUG or CONFIG_SLOB, and blocks stop being aligned. Then
developers have to devise workaround such as own kmem caches with
specified alignment [1], which is not always practical, as recently
evidenced in [2].
The topic has been discussed at LSF/MM 2019 [3]. Adding a
'kmalloc_aligned()' variant would not help with code unknowingly relying
on the implicit alignment. For slab implementations it would either
require creating more kmalloc caches, or allocate a larger size and only
give back part of it. That would be wasteful, especially with a generic
alignment parameter (in contrast with a fixed alignment to size).
Ideally we should provide to mm users what they need without difficult
workarounds or own reimplementations, so let's make the kmalloc()
alignment to size explicitly guaranteed for power-of-two sizes under all
configurations. What this means for the three available allocators?
* SLAB object layout happens to be mostly unchanged by the patch. The
implicitly provided alignment could be compromised with
CONFIG_DEBUG_SLAB due to redzoning, however SLAB disables redzoning for
caches with alignment larger than unsigned long long. Practically on at
least x86 this includes kmalloc caches as they use cache line alignment,
which is larger than that. Still, this patch ensures alignment on all
arches and cache sizes.
* SLUB layout is also unchanged unless redzoning is enabled through
CONFIG_SLUB_DEBUG and boot parameter for the particular kmalloc cache.
With this patch, explicit alignment is guaranteed with redzoning as
well. This will result in more memory being wasted, but that should be
acceptable in a debugging scenario.
* SLOB has no implicit alignment so this patch adds it explicitly for
kmalloc(). The potential downside is increased fragmentation. While
pathological allocation scenarios are certainly possible, in my testing,
after booting a x86_64 kernel+userspace with virtme, around 16MB memory
was consumed by slab pages both before and after the patch, with
difference in the noise.

cgroup v2 introduces two memory protection thresholds: memory.low
(best-effort) and memory.min (hard protection). While they generally do
what they say on the tin, there is a limitation in their implementation
that makes them difficult to use effectively: that cliff behaviour often
manifests when they become eligible for reclaim. This patch implements
more intuitive and usable behaviour, where we gradually mount more
reclaim pressure as cgroups further and further exceed their protection
thresholds.
This cliff edge behaviour happens because we only choose whether or not
to reclaim based on whether the memcg is within its protection limits
(see the use of mem_cgroup_protected in shrink_node), but we don't vary
our reclaim behaviour based on this information. Imagine the following
timeline, with the numbers the lruvec size in this zone:
1. memory.low=1000000, memory.current=999999. 0 pages may be scanned.
2. memory.low=1000000, memory.current=1000000. 0 pages may be scanned.
3. memory.low=1000000, memory.current=1000001. 1000001* pages may be
scanned. (?!)
* Of course, we won't usually scan all available pages in the zone even
without this patch because of scan control priority, over-reclaim
protection, etc. However, as shown by the tests at the end, these
techniques don't sufficiently throttle such an extreme change in input,
so cliff-like behaviour isn't really averted by their existence alone.
Here's an example of how this plays out in practice. At Facebook, we are
trying to protect various workloads from "system" software, like
configuration management tools, metric collectors, etc (see this[0] case
study). In order to find a suitable memory.low value, we start by
determining the expected memory range within which the workload will be
comfortable operating. This isn't an exact science -- memory usage deemed
"comfortable" will vary over time due to user behaviour, differences in
composition of work, etc, etc. As such we need to ballpark memory.low,
but doing this is currently problematic:
1. If we end up setting it too low for the workload, it won't have
*any* effect (see discussion above). The group will receive the full
weight of reclaim and won't have any priority while competing with the
less important system software, as if we had no memory.low configured
at all.
2. Because of this behaviour, we end up erring on the side of setting
it too high, such that the comfort range is reliably covered. However,
protected memory is completely unavailable to the rest of the system,
so we might cause undue memory and IO pressure there when we *know* we
have some elasticity in the workload.
3. Even if we get the value totally right, smack in the middle of the
comfort zone, we get extreme jumps between no pressure and full
pressure that cause unpredictable pressure spikes in the workload due
to the current binary reclaim behaviour.
With this patch, we can set it to our ballpark estimation without too much
worry. Any undesirable behaviour, such as too much or too little reclaim
pressure on the workload or system will be proportional to how far our
estimation is off. This means we can set memory.low much more
conservatively and thus waste less resources *without* the risk of the
workload falling off a cliff if we overshoot.
As a more abstract technical description, this unintuitive behaviour
results in having to give high-priority workloads a large protection
buffer on top of their expected usage to function reliably, as otherwise
we have abrupt periods of dramatically increased memory pressure which
hamper performance. Having to set these thresholds so high wastes
resources and generally works against the principle of work conservation.
In addition, having proportional memory reclaim behaviour has other
benefits. Most notably, before this patch it's basically mandatory to set
memory.low to a higher than desirable value because otherwise as soon as
you exceed memory.low, all protection is lost, and all pages are eligible
to scan again. By contrast, having a gradual ramp in reclaim pressure
means that you now still get some protection when thresholds are exceeded,
which means that one can now be more comfortable setting memory.low to
lower values without worrying that all protection will be lost. This is
important because workingset size is really hard to know exactly,
especially with variable workloads, so at least getting *some* protection
if your workingset size grows larger than you expect increases user
confidence in setting memory.low without a huge buffer on top being
needed.
Thanks a lot to Johannes Weiner and Tejun Heo for their advice and
assistance in thinking about how to make this work better.
In testing these changes, I intended to verify that:
1. Changes in page scanning become gradual and proportional instead of
binary.
To test this, I experimented stepping further and further down
memory.low protection on a workload that floats around 19G workingset
when under memory.low protection, watching page scan rates for the
workload cgroup:
+------------+-----------------+--------------------+--------------+
| memory.low | test (pgscan/s) | control (pgscan/s) | % of control |
+------------+-----------------+--------------------+--------------+
| 21G | 0 | 0 | N/A |
| 17G | 867 | 3799 | 23% |
| 12G | 1203 | 3543 | 34% |
| 8G | 2534 | 3979 | 64% |
| 4G | 3980 | 4147 | 96% |
| 0 | 3799 | 3980 | 95% |
+------------+-----------------+--------------------+--------------+
As you can see, the test kernel (with a kernel containing this
patch) ramps up page scanning significantly more gradually than the
control kernel (without this patch).
2. More gradual ramp up in reclaim aggression doesn't result in
premature OOMs.
To test this, I wrote a script that slowly increments the number of
pages held by stress(1)'s --vm-keep mode until a production system
entered severe overall memory contention. This script runs in a highly
protected slice taking up the majority of available system memory.
Watching vmstat revealed that page scanning continued essentially
nominally between test and control, without causing forward reclaim
progress to become arrested.

Currently execution of panic() continues until Xen's panic notifier
(xen_panic_event()) is called at which point we make a hypercall that
never returns.
This means that any notifier that is supposed to be called later as
well as significant part of panic() code (such as pstore writes from
kmsg_dump()) is never executed.
There is no reason for xen_panic_event() to be this last point in
execution since panic()'s emergency_restart() will call into
xen_emergency_restart() from where we can perform our hypercall.
Nevertheless, we will provide xen_legacy_crash boot option that will
preserve original behavior during crash. This option could be used,
for example, if running kernel dumper (which happens after panic
notifiers) is undesirable.

In commit 43d8ce9d65 ("Provide in-kernel headers to make
extending kernel easier") a new mechanism was introduced, for kernels
>=5.2, which embeds the kernel headers in the kernel image or a module
and exposes them in procfs for use by userland tools.
The archive containing the header files has nondeterminism caused by
header files metadata. This patch normalizes the metadata and utilizes
KBUILD_BUILD_TIMESTAMP if provided and otherwise falls back to the
default behaviour.
In commit f7b101d330 ("kheaders: Move from proc to sysfs") it was
modified to use sysfs and the script for generation of the archive was
renamed to what is being patched.

Pull kernel lockdown mode from James Morris:
"This is the latest iteration of the kernel lockdown patchset, from
Matthew Garrett, David Howells and others.
From the original description:
This patchset introduces an optional kernel lockdown feature,
intended to strengthen the boundary between UID 0 and the kernel.
When enabled, various pieces of kernel functionality are restricted.
Applications that rely on low-level access to either hardware or the
kernel may cease working as a result - therefore this should not be
enabled without appropriate evaluation beforehand.
The majority of mainstream distributions have been carrying variants
of this patchset for many years now, so there's value in providing a
doesn't meet every distribution requirement, but gets us much closer
to not requiring external patches.
There are two major changes since this was last proposed for mainline:
- Separating lockdown from EFI secure boot. Background discussion is
covered here: https://lwn.net/Articles/751061/
- Implementation as an LSM, with a default stackable lockdown LSM
module. This allows the lockdown feature to be policy-driven,
rather than encoding an implicit policy within the mechanism.
The new locked_down LSM hook is provided to allow LSMs to make a
policy decision around whether kernel functionality that would allow
tampering with or examining the runtime state of the kernel should be
permitted.
The included lockdown LSM provides an implementation with a simple
policy intended for general purpose use. This policy provides a coarse
level of granularity, controllable via the kernel command line:
lockdown={integrity|confidentiality}
Enable the kernel lockdown feature. If set to integrity, kernel features
that allow userland to modify the running kernel are disabled. If set to
confidentiality, kernel features that allow userland to extract
confidential information from the kernel are also disabled.
This may also be controlled via /sys/kernel/security/lockdown and
overriden by kernel configuration.
New or existing LSMs may implement finer-grained controls of the
lockdown features. Refer to the lockdown_reason documentation in
include/linux/security.h for details.
The lockdown feature has had signficant design feedback and review
across many subsystems. This code has been in linux-next for some
weeks, with a few fixes applied along the way.
Stephen Rothwell noted that commit 9d1f8be5cf ("bpf: Restrict bpf
when kernel lockdown is in confidentiality mode") is missing a

"The major feature in this time is IMA support for measuring and
appraising appended file signatures. In addition are a couple of bug
fixes and code cleanup to use struct_size().
In addition to the PE/COFF and IMA xattr signatures, the kexec kernel
image may be signed with an appended signature, using the same
scripts/sign-file tool that is used to sign kernel modules.
Similarly, the initramfs may contain an appended signature.
This contained a lot of refactoring of the existing appended signature
verification code, so that IMA could retain the existing framework of
calculating the file hash once, storing it in the IMA measurement list
and extending the TPM, verifying the file's integrity based on a file
hash or signature (eg. xattrs), and adding an audit record containing
the file hash, all based on policy. (The IMA support for appended
signatures patch set was posted and reviewed 11 times.)
The support for appended signature paves the way for adding other
signature verification methods, such as fs-verity, based on a single
system-wide policy. The file hash used for verifying the signature and
the signature, itself, can be included in the IMA measurement list"

Merge tag 'virtio-fs-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse virtio-fs support from Miklos Szeredi:
"Virtio-fs allows exporting directory trees on the host and mounting
them in guest(s).
This isn't actually a new filesystem, but a glue layer between the
fuse filesystem and a virtio based back-end.
It's similar in functionality to the existing virtio-9p solution, but
significantly faster in benchmarks and has better POSIX compliance.
Further permformance improvements can be achieved by sharing the page
cache between host and guest, allowing for faster I/O and reduced
memory use.
Kata Containers have been including the out-of-tree virtio-fs (with
the shared page cache patches as well) since version 1.7 as an
experimental feature. They have been active in development and plan to
switch from virtio-9p to virtio-fs as their default solution. There
has been interest from other sources as well.
The userspace infrastructure is slated to be merged into qemu once the
kernel part hits mainline.
This was developed by Vivek Goyal, Dave Gilbert and Stefan Hajnoczi"

The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.

Cgroup v1 memcg controller has exposed a dedicated kmem limit to users
which turned out to be really a bad idea because there are paths which
cannot shrink the kernel memory usage enough to get below the limit (e.g.
because the accounted memory is not reclaimable). There are cases when
the failure is even not allowed (e.g. __GFP_NOFAIL). This means that the
kmem limit is in excess to the hard limit without any way to shrink and
thus completely useless. OOM killer cannot be invoked to handle the
situation because that would lead to a premature oom killing.
As a result many places might see ENOMEM returning from kmalloc and result
in unexpected errors. E.g. a global OOM killer when there is a lot of
free memory because ENOMEM is translated into VM_FAULT_OOM in #PF path and
therefore pagefault_out_of_memory would result in OOM killer.
Please note that the kernel memory is still accounted to the overall limit
along with the user memory so removing the kmem specific limit should
still allow to contain kernel memory consumption. Unlike the kmem one,
though, it invokes memory reclaim and targeted memcg oom killing if
necessary.
Start the deprecation process by crying to the kernel log. Let's see
whether there are relevant usecases and simply return to EINVAL in the
second stage if nobody complains in few releases.

The debug_pagealloc functionality is useful to catch buggy page allocator
users that cause e.g. use after free or double free. When page
inconsistency is detected, debugging is often simpler by knowing the call
stack of process that last allocated and freed the page. When page_owner
is also enabled, we record the allocation stack trace, but not freeing.
This patch therefore adds recording of freeing process stack trace to page
owner info, if both page_owner and debug_pagealloc are configured and
enabled. With only page_owner enabled, this info is not useful for the
memory leak debugging use case. dump_page() is adjusted to print the
info. An example result of calling __free_pages() twice may look like
this (note the page last free stack trace):

Currently, a value of '1" is written to /sys/kernel/slab/<slab>/shrink
file to shrink the slab by flushing out all the per-cpu slabs and free
slabs in partial lists. This can be useful to squeeze out a bit more
memory under extreme condition as well as making the active object counts
in /proc/slabinfo more accurate.
This usually applies only to the root caches, as the SLUB_MEMCG_SYSFS_ON
option is usually not enabled and "slub_memcg_sysfs=1" not set. Even if
memcg sysfs is turned on, it is too cumbersome and impractical to manage
all those per-memcg sysfs files in a real production system.
So there is no practical way to shrink memcg caches. Fix this by enabling
a proper write to the shrink sysfs file of the root cache to scan all the
available memcg caches and shrink them as well. For a non-root memcg
cache (when SLUB_MEMCG_SYSFS_ON or slub_memcg_sysfs is on), only that
cache will be shrunk when written.
On a 2-socket 64-core 256-thread arm64 system with 64k page after
a parallel kernel build, the the amount of memory occupied by slabs
before shrinking slabs were:
# grep task_struct /proc/slabinfo
task_struct 53137 53192 4288 61 4 : tunables 0 0
0 : slabdata 872 872 0
# grep "^S[lRU]" /proc/meminfo
Slab: 3936832 kB
SReclaimable: 399104 kB
SUnreclaim: 3537728 kB
After shrinking slabs (by echoing "1" to all shrink files):
# grep "^S[lRU]" /proc/meminfo
Slab: 1356288 kB
SReclaimable: 263296 kB
SUnreclaim: 1092992 kB
# grep task_struct /proc/slabinfo
task_struct 2764 6832 4288 61 4 : tunables 0 0

Summary of modules changes for the 5.4 merge window:
- Introduce exported symbol namespaces.
This new feature allows subsystem maintainers to partition and
categorize their exported symbols into explicit namespaces. Module
authors are now required to import the namespaces they need.
Some of the main motivations of this feature include: allowing kernel
developers to better manage the export surface, allow subsystem
maintainers to explicitly state that usage of some exported symbols
should only be limited to certain users (think: inter-module or
inter-driver symbols, debugging symbols, etc), as well as more easily
limiting the availability of namespaced symbols to other parts of the
kernel. With the module import requirement, it is also easier to spot
the misuse of exported symbols during patch review. Two new macros are
introduced: EXPORT_SYMBOL_NS() and EXPORT_SYMBOL_NS_GPL(). The API is
thoroughly documented in Documentation/kbuild/namespaces.rst.
- Some small code and kbuild cleanups here and there.

Pull modules updates from Jessica Yu:
"The main bulk of this pull request introduces a new exported symbol
namespaces feature. The number of exported symbols is increasingly
growing with each release (we're at about 31k exports as of 5.3-rc7)
and we currently have no way of visualizing how these symbols are
"clustered" or making sense of this huge export surface.
Namespacing exported symbols allows kernel developers to more
explicitly partition and categorize exported symbols, as well as more
easily limiting the availability of namespaced symbols to other parts
of the kernel. For starters, we have introduced the USB_STORAGE
namespace to demonstrate the API's usage. I have briefly summarized
the feature and its main motivations in the tag below.

kernel developers to better manage the export surface, allow
subsystem maintainers to explicitly state that usage of some
exported symbols should only be limited to certain users (think:
inter-module or inter-driver symbols, debugging symbols, etc), as
well as more easily limiting the availability of namespaced symbols
to other parts of the kernel.
With the module import requirement, it is also easier to spot the
misuse of exported symbols during patch review.
Two new macros are introduced: EXPORT_SYMBOL_NS() and
EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in
Documentation/kbuild/namespaces.rst.

about the state of the extent status cache.
Dropped workaround for pre-1970 dates which were encoded incorrectly
in pre-4.4 kernels. Since both the kernel correctly generates, and
e2fsck detects and fixes this issue for the past four years, it'e time
to drop the workaround. (Also, it's not like files with dates in the
distant past were all that common in the first place.)

This is more cleanup and consolidation of the hmm APIs and the very
strongly related mmu_notifier interfaces. Many places across the tree
using these interfaces are touched in the process. Beyond that a cleanup
to the page walker API and a few memremap related changes round out the
series:
- General improvement of hmm_range_fault() and related APIs, more
documentation, bug fixes from testing, API simplification &
consolidation, and unused API removal
- Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
make them internal kconfig selects
- Hoist a lot of code related to mmu notifier attachment out of drivers by
using a refcount get/put attachment idiom and remove the convoluted
mmu_notifier_unregister_no_release() and related APIs.
- General API improvement for the migrate_vma API and revision of its only
user in nouveau
- Annotate mmu_notifiers with lockdep and sleeping region debugging
Two series unrelated to HMM or mmu_notifiers came along due to
dependencies:
- Allow pagemap's memremap_pages family of APIs to work without providing
a struct device
- Make walk_page_range() and related use a constant structure for function

The `adi,disable-energy-detect` property was implemented in an initial
version of the `adin` driver series, but after a review it was discarded in
favor of implementing the ETHTOOL_PHY_EDPD phy-tunable option.
With the ETHTOOL_PHY_EDPD control, it's possible to disable/enable
Energy-Detect-Power-Down for the `adin` PHY, so this device-tree is not
needed.

The 'mac-mode' property is similar to 'phy-mode' and 'phy-connection-type',
which are enums of mode strings.
The 'dwmac' driver supports almost all modes declared in the 'phy-mode'
enum (except for 1 or 2). But in general, there may be a case where
'mac-mode' becomes more generic and is moved as part of phylib or netdev.
In any case, the 'mac-mode' field should be made an enum, and it also makes
sense to just reference the 'phy-connection-type' from
'ethernet-controller.yaml'. That will also make it more future-proof for new
modes.

After many years, support for the MMP2 based OLPC XO-1.75 finally makes

clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:
- Add regulator support to the cdce925 clk driver
- Add support for Raspberry Pi 4 bcm2711 SoCs
- Add SDIO gate support to aspeed driver
- Add missing of_node_put() calls in various clk drivers
- Migrate Amlogic driver to new clock parent description method
- Add DVFS support to Amlogic Meson g12
- Add Amlogic Meson g12a reset support to the axg audio clock controller
- Add sm1 support to the Amlogic Meson g12a clock controller
- Switch i.MX8MM clock driver to platform driver
- Add Hifi4 DSP related clocks for i.MX8QXP SoC
- Fix Audio PLL setting and parent clock for USB
- Misc i.MX8 clock driver improvements and corrections
- Set floor ops for Qualcomm SD clks so that rounding works
- Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"We have a small collection of core framework updates this time, mostly
around clk registration by clk providers and debugfs "nice to haves"
for rate constraints. I'll highlight that we're now setting the
clk_init_data pointer inside struct clk_hw to NULL during
clk_register(), which may break some drivers that thought they could
use that pointer during normal operations. That change has been
sitting in next for a while now but maybe something is still broken.
We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support,
new features for existing drivers, and bug fixes scattered throughout.
The biggest diffstat is the Amlogic driver that gained CPU clk support
in addition to migrating to the new way of specifying clk parents.
After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
support for various new SoCs and clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:
- Add regulator support to the cdce925 clk driver
- Add support for Raspberry Pi 4 bcm2711 SoCs
- Add SDIO gate support to aspeed driver
- Add missing of_node_put() calls in various clk drivers
- Migrate Amlogic driver to new clock parent description method
- Add DVFS support to Amlogic Meson g12
- Add Amlogic Meson g12a reset support to the axg audio clock controller
- Add sm1 support to the Amlogic Meson g12a clock controller
- Switch i.MX8MM clock driver to platform driver
- Add Hifi4 DSP related clocks for i.MX8QXP SoC
- Fix Audio PLL setting and parent clock for USB
- Misc i.MX8 clock driver improvements and corrections
- Set floor ops for Qualcomm SD clks so that rounding works
- Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
- Enable the Allwinner V3 SoC and fix the i2s clock for H6"

The documentation of skew values for the KSZ9021 PHY was misleading
because the driver implementation followed the erroneous information
given in the original KSZ9021 datasheet before it was corrected in
revision 1.2 (Feb 2014). It is probably too late to correct the driver
now because of the many existing device trees, so instead this just
corrects the documentation to explain that what you actually get is not
what you might think when looking at the device tree.

"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the
week but got delayed writing summary and sending it out, due to a mix
of sick kid and jetlag!
There are some fixes pending, but I'd rather get the main merge out of
the way instead of delaying it longer.
It's also pretty large in commit count and new amd header file size.
The largest thing is four new amdgpu products (navi12/14, arcturus and
renoir APU support).
Otherwise it's pretty much lots of work across the board, i915 has
started landing tigerlake support, lots of icelake fixes and lots of

Please consider pulling fs-verity for 5.4.
fs-verity is a filesystem feature that provides Merkle tree based
hashing (similar to dm-verity) for individual readonly files, mainly for
the purpose of efficient authenticity verification.
This pull request includes:
(a) The fs/verity/ support layer and documentation.
(b) fs-verity support for ext4 and f2fs.
Compared to the original fs-verity patchset from last year, the UAPI to
enable fs-verity on a file has been greatly simplified. Lots of other
things were cleaned up too.
fs-verity is planned to be used by two different projects on Android;
most of the userspace code is in place already. Another userspace tool
("fsverity-utils"), and xfstests, are also available. e2fsprogs and
f2fs-tools already have fs-verity support. Other people have shown
interest in using fs-verity too.
I've tested this on ext4 and f2fs with xfstests, both the existing tests
and the new fs-verity tests. This has also been in linux-next since
July 30 with no reported issues except a couple minor ones I found
myself and folded in fixes for.
Ted and I will be co-maintaining fs-verity.

This is a large update to fs/crypto/ which includes:
- Add ioctls that add/remove encryption keys to/from a filesystem-level
keyring. These fix user-reported issues where e.g. an encrypted home
directory can break NetworkManager, sshd, Docker, etc. because they
don't get access to the needed keyring. These ioctls also provide a
way to lock encrypted directories that doesn't use the vm.drop_caches
sysctl, so is faster, more reliable, and doesn't always need root.
- Add a new encryption policy version ("v2") which switches to a more
standard, secure, and flexible key derivation function, and starts
verifying that the correct key was supplied before using it. The key
derivation improvement is needed for its own sake as well as for
ongoing feature work for which the current way is too inflexible.
Work is in progress to update both Android and the 'fscrypt' userspace
tool to use both these features. (Working patches are available and
just need to be reviewed+merged.) Chrome OS will likely use them too.
This has also been tested on ext4, f2fs, and ubifs with xfstests -- both
the existing encryption tests, and the new tests for this. This has
also been in linux-next since Aug 16 with no reported issues. I'm also
using an fscrypt v2-encrypted home directory on my personal desktop.

- greybus core code moved out of staging
Along with that, a new filesytem has been added:

transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots

probably doesn't work at all given that the maintainers left many many
years ago. So move it to staging where it will be removed in a few
releases if no one screams.
Other than that, lots of little things. The usual gadget and xhci and

Here is the big driver core update for 5.4-rc1.
There was a bit of a churn in here, with a number of core and OF
platform patches being added to the tree, and then after much discussion
and review and a day-long in-person meeting, they were decided to be
reverted and a new set of patches is currently being reviewed on the
mailing list.
Other than that churn, there are two "persistent" branches in here that
other trees will be pulling in as well during the merge window. One
branch to add support for drivers to have the driver core automatically
add sysfs attribute files when a driver is bound to a device so that the
driver doesn't have to manually do it (and then clean it up, as it
always gets it wrong).
There's another branch in here for generic lookup helpers for the driver
core that lots of busses are starting to use. That's the majority of
the non-driver-core changes in this patch series.
There's also some on-going debugfs file creation cleanup that has been
slowly happening over the past few releases, with the goal to hopefully
get that done sometime next year.
All of these have been in linux-next for a while now with no reported

Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.
LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway
- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name
- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name
- update following drivers and their DT bindings to use the new LED
registration API:
- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
Other LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug
- ledtrig-gpio:
- GPIO 0 is valid
Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:
- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return
- leds-pwm, leds-is31fl32xx:
- use struct_size() helper
- leds-lm3697, leds-lm36274, leds-lm3532:
- switch to use fwnode_property_count_uXX()
- leds-lm3532:
- fix brightness control for i2c mode
- change the define for the fs current register
- fixes for the driver for stability
- add full scale current configuration
- dt: Add property for full scale current.
- avoid potentially unpaired regulator calls
- move static keyword to the front of declarations
- fix optional led-max-microamp prop error handling
- leds-max77650:
- add of_node_put() before return
- add MODULE_ALIAS()
- Switch to fwnode property API
- leds-as3645a:
- fix misuse of strlcpy
- leds-netxbig:
- add of_node_put() in netxbig_leds_get_of_pdata()
- remove legacy board-file support
- leds-is31fl319x:
- simplify getting the adapter of a client
- leds-ti-lmu-common:
- fix coccinelle issue
- move static keyword to the front of declaration
- leds-syscon:
- use resource managed variant of device register
- leds-ktd2692:

As shown in diffstat and logs, it was again a busy development
cycle at this time, too. The most significant changes are still
on-going refactoring / modernization works for ASoC core and
drivers, but there are lots of other changes as well. Here we go,
some highlights below:
ASoC:
- Quite lots of cleanup / refactoring of ASoC core and APIs;
most of them are systematic, but also including cleanups and
modernization
- A bulk of updates for some ASoC platforms, Freescale, sunxi and
Intel SST/SOF
- Initial support for Sound Open Firmware on i.MX8
- Removal of deprecated w90x900 and nuc900 drivers
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
7ULP and 8MQ, Meson G12A and NXP UDA1334
USB-audio:
- More validations of descriptor units for hardening against bugs
reported by fuzzers
- PCM device assignment workaround for a past call-order change
- Scarlett Gen2 mixer interface, a few more more quirks
HD-audio:
- Support for audio component with AMD/ATI and Nvidia HDMI codecs
- Clean up HD-audio core and remove indirect access ops for Intel SOF
- DMIC detection at probe; it would make systems automatically falling
back to SST/SOF driver on devices that need DMIC handling.
Needs a new Kconfig to set, and beware that it's still new and a bit
experimental
FireWire:
- Lots of code refactoring and cleanups

RST conversion is happily mostly behind us.
- A new document on reproducible builds.
- We finally got around to zapping the documentation for hardware support
that was removed in 2004; one doesn't want to rush these things.
- The usual assortment of fixes, typo corrections, etc.
You'll still find a handful of annoying conflicts against other trees,
mostly tied to the last RST conversions; resolutions are straightforward
and the linux-next ones are good.

Pull core timer updates from Thomas Gleixner:
"Timers and timekeeping updates:
- A large overhaul of the posix CPU timer code which is a preparation
for moving the CPU timer expiry out into task work so it can be
properly accounted on the task/process.
An update to the bogus permission checks will come later during the
merge window as feedback was not complete before heading of for
travel.
- Switch the timerqueue code to use cached rbtrees and get rid of the
homebrewn caching of the leftmost node.
- Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
single function
- Implement the separation of hrtimers to be forced to expire in hard
interrupt context even when PREEMPT_RT is enabled and mark the
affected timers accordingly.
- Implement a mechanism for hrtimers and the timer wheel to protect
RT against priority inversion and live lock issues when a (hr)timer
which should be canceled is currently executing the callback.
Instead of infinitely spinning, the task which tries to cancel the
timer blocks on a per cpu base expiry lock which is held and
released by the (hr)timer expiry code.
- Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
resulting in faster access to timekeeping functions.
- Updates to various clocksource/clockevent drivers and their device
tree bindings.
- The usual small improvements all over the place"

linecount generated by scripts/get_maintainer.pl. :-)
- Add another series of patches that brings the -rt (PREEMPT_RT) tree
closer to mainline: split the monolithic CONFIG_PREEMPT dependencies
into a new CONFIG_PREEMPTION category that will allow the eventual
introduction of CONFIG_PREEMPT_RT. Still a few more hundred patches
to go though.
- Extend the CPU cgroup controller with uclamp.min and uclamp.max to
allow the finer shaping of CPU bandwidth usage.
- Micro-optimize energy-aware wake-ups from O(CPUS^2) to O(CPUS).
- Improve the behavior of high CPU count, high thread count
applications running under cpu.cfs_quota_us constraints.
- Improve balancing with SCHED_IDLE (SCHED_BATCH) tasks present.
- Improve CPU isolation housekeeping CPU allocation NUMA locality.
- Fix deadline scheduler bandwidth calculations and logic when cpusets
rebuilds the topology, or when it gets deadline-throttled while it's
being offlined.
- Convert the cpuset_mutex to percpu_rwsem, to allow it to be used from
setscheduler() system calls without creating global serialization.
Add new synchronization between cpuset topology-changing events and
the deadline acceptance tests in setscheduler(), which were broken
before.
- Rework the active_mm state machine to be less confusing and more
optimal.
- Rework (simplify) the pick_next_task() slowpath.

This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit respectively.
There are lots of cleanups and additional hardware support for platforms
we already support based on SoCs from Renesas, ST-Microelectronics,
Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
usually paired with an external 5G modem. So far we only support the
Qualcomm SM8150 MTP reference platform, but no actual products.
For the slightly older Qualcomm platforms, support for several interesting
products is getting added: Three laptops based on Snapdragon 835/MSM8998
(Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
aka Android One 2nd gen "seed" aka Wileyfox Swift).
Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
Allwinner V3 is a repackaged version of the existing low-end V3s chip,
and is used in the tiny Lichee Pi Zero plus, also added here. There is
also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
eMMC variant of the Olimex A64-Olinuxino development board.
NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
similar to the i.MX8M Mini. As usual, there is a large number of new
boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
set-top-box line and smart speaker with newer CPU and GPU cores compared
to their predecessors. Both are now also supported by the Khadas VIM3
development board series, and the dts files for that get reorganized a
bit to better deal with all variants. Another board based on SM1 that
gets added is the SEI Robotics SEI610.
There are a handful of new x86 and Power9 server boards using Aspeed BMC
chips that are gaining support for running Linux on the BMC through the
OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
and Mihawk. Notably these are still new machines using SoCs based on
the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
AST2600 is still ramping up.
There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
(digital signage, PoS, ...).
One more single-board computer based on the popular 64-bit RK3399 is
added: the Leez RK3399 P710.

The branch contains driver changes that are tightly
connected to SoC specific code. Aside from smaller
cleanups and bug fixes, here is a list of the notable
changes.
New device drivers:
- The Turris Mox router has a new "moxtet" bus driver
for its on-board pluggable extension bus. The
same platform also gains a firmware driver.
- The Samsung Exynos family gains a new Chipid driver
exporting using the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon
chips.
- A firmware driver for the NXP i.MX DSP IPC protocol
using shared memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the
NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for
the S905X3 and A311D chips
- A rework of the TI Davinci framebuffer driver to
allow important cleanups in the platform code
- A couple of device drivers for removed ARM SoC
platforms are removed. Most of the removals were
picked up by other maintainers, this contains
whatever was left.

The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel

using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still in
active use and are converted to the ARCH_MULTIPLATFORM build, meaning
that we can compile a kernel that works on these along with most other
ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
but additional work is needed to complete this. Patches for the
remaining ARMv5 platforms have started but need more work and some
testing.
Support for the new ASpeed AST2600 gets added, this is based on the

[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"Although there isn't tonnes of code in terms of line count, there are
a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.
Summary:
- 52-bit virtual addressing in the kernel
- New ABI to allow tagged user pointers to be dereferenced by
syscalls
- Early RNG seeding by the bootloader
- Improve robustness of SMP boot

v5.4 kernel cycle.
Core changes:
- Support hierarchical GPIO irqchips. We now have three
consumers that can use this: Intel IXP4xx, ThunderX and
Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
code has been long in the making and hashed out so it should
be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip
is used at the topmost irq controller at least, as the
hierarchical irqchip requires strict hierarchy all the
way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a
.init_valid_mask() callback in the main chip or GPIO interrupt
chip respectively. Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code
out in its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does
not hurt to keep the include items around, and we get
quicker and clearer compile failures if the appropriate
kernel symbols are not selected for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted
from arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and
CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling
in the struct instead of using set-up functions (the new
way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the
GPIO tree last cycle so let's mop up the shards.

The big theme for this release has been performance, we've had a series
of unrelated overhauls of a few drivers all with a big peformance
component. Otherwise it's been relatively quiet, highlights include:
- A big overhaul of the spi-fsl-dspi driver improving the code quality,
performance and stability from Vladimir Oltean.
- A big performance enhancement for the bc2835 (Raspberry Pi) driver
for unidirectional transfers from Lukas Wunner.
- Improved performance on small transfers for the uniphier driver from
Keiji Hayashibara.
- Lots of coccinelle generated cleanups from Yue Haibing.
- New device support for Freescale ls2080a and Nuvoton NPCM FIU.

A small update for the regualtor API for this cycle, some small fixes
and a bunch of new devices but none of them very big. The most stand
out thing is the regulator-fixed-clock driver which is for regulators
where the enable control is done by using a clock instead of a GPIO or
register write, a novel hardware design that had not previously come up.
- Added a keyword pattern for regulator_get_optional() since usage of
that API generally needs extra review.
- Operating mode and suspend state support for act8865.
- New device support for Active Semiconductor ACT8600 chargers,

Make client use osd reply and session message to infer if itself is

is blacklisted. Auto reconnect is limited to once every 30 minutes.
Auto reconnect is disabled by default. It can be enabled/disabled by
recover_session=<no|clean> mount option. In 'clean' mode, client drops
any dirty data/metadata, invalidates page caches and invalidates all
writable file handles. After reconnect, file locks become stale because
MDS loses track of them. If an inode contains any stale file locks,
read/write on the indoe are not allowed until applications release all

Standard integer promotion is already done and %hx and %hhx is useless
so do not encourage the use of %hh[xudi] or %h[xudi].
As Linus said in:
https://lore.kernel.org/lkml/CAHk-=wgoxnmsj8GEVFJSvTwdnWm8wVJthefNk2n6+4TC=20e0Q@mail.gmail.com/
It's a pointless warning, making for more complex code, and
making people remember esoteric printf format details that have no
reason for existing.
The "h" and "hh" things should never be used. The only reason for them
being used if if you have an "int", but you want to print it out as a
"char" (and honestly, that is a really bad reason, you'd be better off
just using a proper cast to make the code more obvious).
So if what you have a "char" (or unsigned char) you should always just
print it out as an "int", knowing that the compiler already did the
proper type conversion.

Part of the intention during the definition of the RISC-V kernel image
header was to lay the groundwork for a future merge with the ARM64
image header. One error during my original review was not noticing
that the RISC-V header's "magic" field was at a different size and
position than the ARM64's "magic" field. If the existing ARM64 Image
header parsing code were to attempt to parse an existing RISC-V kernel
image header format, it would see a magic number 0. This is
undesirable, since it's our intention to align as closely as possible
with the ARM64 header format. Another problem was that the original
"res3" field was not being initialized correctly to zero.
Address these issues by creating a 32-bit "magic2" field in the RISC-V
header which matches the ARM64 "magic" field. RISC-V binaries will
store "RSC\x05" in this field. The intention is that the use of the
existing 64-bit "magic" field in the RISC-V header will be deprecated
over time. Increment the minor version number of the file format to
indicate this change, and update the documentation accordingly. Fix
the assembler directives in head.S to ensure that reserved fields are
properly zero-initialized.

Add the dm-clone target, which allows cloning of arbitrary block
devices.
dm-clone produces a one-to-one copy of an existing, read-only source
device into a writable destination device: It presents a virtual block
device which makes all data appear immediately, and redirects reads and
writes accordingly.
The main use case of dm-clone is to clone a potentially remote,
high-latency, read-only, archival-type block device into a writable,
fast, primary-type device for fast, low-latency I/O. The cloned device
is visible/mountable immediately and the copy of the source device to
the destination device happens in the background, in parallel with user
I/O.
When the cloning completes, the dm-clone table can be removed altogether
and be replaced, e.g., by a linear table, mapping directly to the
destination device.
For further information and examples of how to use dm-clone, please read
Documentation/admin-guide/device-mapper/dm-clone.rst

PPC KVM update for 5.4
- Some prep for extending the uses of the rmap array
- Various minor fixes
- Commits from the powerpc topic/ppc-kvm branch, which fix a problem
with interrupts arriving after free_irq, causing host hangs and crashes.
Quite a big update this time around, particularly in the core
where we've had a lot of cleanups from Morimoto-san - there's
not much functional change but quite a bit of modernization
going on. We've also seen a lot of driver work, a lot of it
cleanups but also some particular drivers.
- Lots and lots of cleanups from Morimoto-san and Yue Haibing.
- Lots of cleanups and enhancements to the Freescale, sunxi dnd
Intel rivers.
- Initial Sound Open Firmware suppot for i.MX8.
- Removal of w90x900 and nuc900 drivers as the platforms are
being removed.
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale
i.MX 7ULP and 8MQ, Meson G12A and NXP UDA1334

This adds the documentation to the compatible regulator-fixed-clock.
This binding is a special binding of regulator-fixed and adds the
ability to add a clock to regulator-fixed, so the regulator can be
enabled and disabled with that clock. If the special compatible
regulator-fixed-clock is used it is mandatory to supply a clock.
