Hi Linus,

Please pull Kbuild updates for v5.15-rc1.


This pull request is randomly touching many files in the tree,
most of which are <stdarg.h> cleanups.


After pulling this, you may see new warnings like this:

    arch/x86/entry/vdso/Makefile:135: FORCE prerequisite is missing

They are just trivial Makefile mistakes, and patches
already exist. So, they will be fixed sooner or later.



Thanks.




The following changes since commit 36a21d51725af2ce0700c6ebcb6b9594aac658a6:

  checkkconfigsymbols.py: Fix the '--ignore' option (2021-08-27 14:07:07 +0900)

----------------------------------------------------------------
Kbuild updates for v5.15

 - Add -s option (strict mode) to merge_config.sh to make it fail when
   any symbol is redefined.

 - Show a warning if a different compiler is used for building external
   modules.

 - Infer --target from ARCH for CC=clang to let you cross-compile the
   kernel without CROSS_COMPILE.

 - Make the integrated assembler default (LLVM_IAS=1) for CC=clang.

 - Add <linux/stdarg.h> to the kernel source instead of borrowing
   <stdarg.h> from the compiler.

 - Remove -isystem from the global compiler flag (except nds32) so
   nobody will accidentally include unintended headers.

 - Add Nick Desaulniers as a Kbuild reviewer.

 - Drop stale cc-option tests.

 - Fix the combination of CONFIG_TRIM_UNUSED_KSYMS and CONFIG_LTO_CLANG
   to handle symbols in inline assembly.

 - Show a warning if 'FORCE' is missing for if_changed rules.

 - Various cleanups

I refuse to have new warnings in my tree, particularly during the merge window.

So I will not be pulling this, since I do indeed see those warnings
when doing my test builds.

OK, I will fix the warnings and send v2 shortly.
Thanks.
