c9bfb7b4d9 KVM: arm64: Assume write fault on S1PTW permission fault on instruction fetch
commit c4ad98e4b72cb5be30ea282fce935248f2300e62 upstream.

KVM currently assumes that an instruction abort can never be a write.
This is in general true, except when the abort is triggered by
a S1PTW on instruction fetch that tries to update the S1 page tables
(to set AF, for example).

This can happen if the page tables have been paged out and brought
back in without seeing a direct write to them (they are thus marked
read only), and the fault handling code will make the PT executable(!)
instead of writable. The guest gets stuck forever.

In these conditions, the permission fault must be considered as
a write so that the Stage-1 update can take place. This is essentially
the I-side equivalent of the problem fixed by 60e21a0ef5 ("arm64: KVM:
Take S1 walks into account when determining S2 write faults").

Update kvm_is_write_fault() to return true on IABT+S1PTW, and introduce
kvm_vcpu_trap_is_exec_fault() that only return true when no faulting
on a S1 fault. Additionally, kvm_vcpu_dabt_iss1tw() is renamed to
kvm_vcpu_abt_iss1tw(), as the above makes it plain that it isn't
specific to data abort.

10a144b77f ARM: OMAP2+: Handle errors for cpu_pm
[ Upstream commit 55be2f50336f67800513b46c5ba6270e4ed0e784 ]

We need to check for errors when calling cpu_pm_enter() and
cpu_cluster_pm_enter(). And we need to bail out on errors as
otherwise we can enter a deeper idle state when not desired.

I'm not aware of the lack of error handling causing issues yet,
but we need this at least for blocking deeper idle states when
a GPIO instance has pending interrupts.

47634c0fc9 ARM: 8948/1: Prevent OOB access in stacktrace
[ Upstream commit 40ff1ddb5570284e039e0ff14d7a859a73dc3673 ]

The stacktrace code can read beyond the stack size, when it attempts to
read pt_regs from exception frames.

This can happen on normal, non-corrupt stacks.  Since the unwind
information in the extable is not correct for function prologues, the
unwinding code can return data from the stack which is not actually the
caller function address, and if in_entry_text() happens to succeed on
this value, we can end up reading data from outside the task's stack
when attempting to read pt_regs, since there is no bounds check.

Example:

 [<8010e729>] (unwind_backtrace) from [<8010a9c9>] (show_stack+0x11/0x14)
 [<8010a9c9>] (show_stack) from [<8057d8d7>] (dump_stack+0x87/0xac)

In this example, the stack limit is 0xeb492000, but 16 bytes outside the

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp.
GZIP, BZIP2, LZOP env variables are reserved by the tools. The original
attempt to redefine them internally doesn't work in makefiles/scripts
intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in
broken builds. There can be other broken build commands because of this,
so the universal solution is to use non-reserved env variables for the
compression tools.

37432a83fa kbuild: add variables for compression tools
commit 8dfb61dcbaceb19a5ded5e9c9dcf8d05acc32294 upstream.

Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2

Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.

The credit goes to @grsecurity.

As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"

[ Upstream commit 5656bb3857c4904d1dec6e1b8f876c1c0337274e ]

The timer fixed interval period pulse generator register
is used to generate periodic pulses. The down count
register loads the value programmed in the fixed period
interval (FIPER). At every tick of the timer accumulator
overflow, the counter decrements by the value of
TMR_CTRL[TCLK_PERIOD]. It generates a pulse when the down
counter value reaches zero. It reloads the down counter
in the cycle following a pulse.

To use the TMR_FIPER register to generate desired periodic
pulses. The value should programmed is,
desired_period - tclk_period

Current tmr-fiper2 value is to generate 100us periodic pulses.
(But the value should have been 99995, not 99990. The tclk_period is 5.)
This patch is to generate 1 second periodic pulses with value
999999995 programmed which is more desired by user.

whether invalidate_range_{start,end}() are permitted to block. In the
case of kvm_mmu_notifier_invalidate_range_start(), this field is not
forwarded on to the architecture-specific implementation of
kvm_unmap_hva_range() and therefore the backend cannot sensibly decide
whether or not to block.

Add an extra 'flags' parameter to kvm_unmap_hva_range() so that
architectures are aware as to whether or not they are permitted to block.

35e1338bdd ARM: 8992/1: Fix unwind_frame for clang-built kernels
commit b4d5ec9b39f8b31d98f65bc5577b5d15d93795d7 upstream.

Since clang does not push pc and sp in function prologues, the current
implementation of unwind_frame does not work. By using the previous
frame's lr/fp instead of saved pc/sp we get valid unwinds on clang-built
kernels.

The bounds check on next frame pointer must be changed as well since
there are 8 less bytes between frames.

This fixes /proc/<pid>/stack.

[ Upstream commit e4dae01bf08b754de79072441c357737220b873f ]

The Bananapi M2+ uses a GPIO line to change the effective resistance of
the CPU supply regulator's feedback resistor network. The voltages
described in the device tree were given directly by the vendor. This
turns out to be slightly off compared to the real values.

The updated voltages are based on calculations of the feedback resistor

Call exynos_cpu_power_up(cpunr) unconditionally. This is needed by the
big.LITTLE cpuidle driver and has no side-effects on other code paths.

The additional soft-reset call during little core power up has been added
to properly boot all cores on the Exynos5422-based boards with secure
firmware (like Odroid XU3/XU4 family). This however broke big.LITTLE
CPUidle driver, which worked only on boards without secure firmware (like
Peach-Pit/Pi Chromebooks). Apply the workaround only when board is
running under secure firmware.

[ Upstream commit 92025b90f18d45e26b7f17d68756b1abd771b9d3 ]

The hardware codec on the A10, A10s, A13 and A20 needs buffer in the
first 256MB of RAM. This was solved by setting the CMA pool at a fixed
address in that range.

However, in recent kernels there's something else that comes in and
reserve some range that end up conflicting with our default pool
requirement, and thus makes its reservation fail.

The video codec will then use buffers from the usual default pool,
outside of the range it can access, and will fail to decode anything.

Since we're only concerned about that 256MB, we can however relax the
allocation to just specify the range that's allowed, and not try to
enforce a specific address.

commit eec13b42d41b0f3339dcf0c4da43734427c68620 upstream.

Unprivileged memory accesses generated by the so-called "translated"
instructions (e.g. LDRT) in kernel mode can cause user watchpoints to fire
unexpectedly. In such cases, the hw_breakpoint logic will invoke the user
overflow handler which will typically raise a SIGTRAP back to the current
task. This is futile when returning back to the kernel because (a) the
signal won't have been delivered and (b) userspace can't handle the thing
anyway.

Avoid invoking the user overflow handler for watchpoints triggered by
kernel uaccess routines, and instead single-step over the faulting
instruction as we would if no overflow handler had been installed.

[ Upstream commit ed3e98e919aaaa47e9d9f8a40c3f6f4a22577842 ]

Instead, expose the key via the input framework, as SW_MACHINE_COVER

The chip-detect GPIO is actually detecting if the cover is closed.
Technically it's possible to use the SD card with open cover. The
only downside is risk of battery falling out and user being able
to physically remove the card.

The behaviour of SD card not being available when the device is
open is unexpected and creates more problems than it solves. There
is a high chance, that more people accidentally break their rootfs
by opening the case without physically removing the card.
