Dear stable kernel maintainers,
Please consider the attached mbox file, which contains 9 patches which
cherry pick cleanly onto 5.4:
1. commit fcf1b6a35c16 ("Documentation/llvm: add documentation on
building w/ Clang/LLVM")
2. commit 0f44fbc162b7 ("Documentation/llvm: fix the name of llvm-size")
3. commit 63b903dfebde ("net: wan: wanxl: use allow to pass
CROSS_COMPILE_M68k for rebuilding firmware")
4. commit 734f3719d343 ("net: wan: wanxl: use $(M68KCC) instead of
$(M68KAS) for rebuilding firmware")
5. commit eefb8c124fd9 ("x86/boot: kbuild: allow readelf executable to
be specified")
6. commit 94f7345b7124 ("kbuild: remove PYTHON2 variable")
7. commit aa824e0c962b ("kbuild: remove AS variable")
8. commit 7e20e47c70f8 ("kbuild: replace AS=clang with LLVM_IAS=1")
9. commit a0d1c951ef08 ("kbuild: support LLVM=1 to switch the default
tools to Clang/LLVM")
This series improves/simplifies building kernels with Clang and LLVM
utilities; it will help the various CI systems testing kernels built
with Clang+LLVM utilities (in fact I will be pointing to this, if
accepted, next week at plumbers with those CI system maintainers), and
we will make immediate use of it in Android (see also:
https://android-review.googlesource.com/c/platform/prebuilts/clang/host/linux-x86/+/1405387).
We can always carry it out of tree in Android, but I think the series
is fairly tame, and would prefer not to.
I only particularly care about 5+8+9 (eefb8c124fd9, 7e20e47c70f8, and
a0d1c951ef08), but the rest are required for them to cherry-pick
cleanly. I don't mind separating those three out, though they won't
be clean cherry-picks at that point. It might be good to have
Masahiro review the series. If accepted, I plan to wire up test
coverage of these immediately in
https://github.com/ClangBuiltLinux/continuous-integration/issues/300.
Most of the above landed in v5.7-rc1, with 94f7345b7124 landing in
v5.6-rc1 and eefb8c124fd9 landing in v5.5-rc3.
