From a quick look nothing stands out as requiring changes to kvm tools
such as tools/perf/arch/s390/util/kvm-stat.c.

Due to:
1e61f78baf ("x86/cpufeature: Make sure DISABLED/REQUIRED macros are updated")
No changes to tools using those headers (tools/arch/x86/lib/mem{set,cpu}_64.S)
seems necessary.

There were changes related to the deprecation of the "pcommit"
instruction:
fd1d961dd6 ("x86/insn: remove pcommit")
dfa169bbee ("Revert "KVM: x86: add pcommit support"")
No need to update anything in the tools, as "pcommit" wasn't being
listed on the VMX_EXIT_REASONS in the tools/perf/arch/x86/util/kvm-stat.c
file.
Just grab fresh copies of these files to silence the file cache

We use it in bitops/__ffs.h and bitops/atomic.h, that we also got from
the kernel, but were getting it from either newer systems that carry it
in /usr/include, or from the kernel sources, that we decided not to
touch from tools/ code. Fix it.

Those kernel files were being directly accessed, which we're not
allowing anymore to avoid that changes in the kernel side break tooling.
Warn if these copies drift from the original files.

And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
introduced by eae7a755ee ("perf tools, x86: Build perf on older
user-space as well").
This way we get closer to mirroring the kernel for cases where __NR_
can't be found for some include path/_GNU_SOURCE/whatever scenario.

Uses the arch/x86/ kernel code for x86_64/i386, fallbacking to a gcc
intrinsics implementation that has been tested in at least sparc64.
Will be used for reference counting in tools/perf.
