Linux kernel source tree for SHARP Brain series (PW-SH1 or later)
5c4d7c82c0
As it is not normally available on x86_64 not being tested on test-all.c
but being in FEATURE_TESTS_BASIC ends up implying that those features
are present, which leads to trying to link with those libraries and a
build failure now that test-all.c is finally again building
successfully:
/usr/bin/ld: cannot find -lunwind-x86
/usr/bin/ld: cannot find -lunwind-aarch64
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:199: /tmp/build/perf/plugin_jbd2.so] Error 1
make[3]: *** Waiting for unfinished jobs....
/usr/bin/ld: cannot find -lunwind-x86
/usr/bin/ld: cannot find -lunwind-aarch64
So remove those features from there and explicitely test them.
And then move this patch to just before the last one that allows this to
be exposed, so that we keep the tree bisectable.
With all this in place we get, at this point:

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
