Subject: [GIT PULL] Kbuild updates for v5.15-rc1
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
