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.
Detected by the tools build header drift checker:

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
coherency detector:
$ make -C tools/perf O=/tmp/build/perf install-bin

Which is just a wrapper for sys_getcpu and is not present in at least
musl libc.

We can't access kernel files directly from tools/, so copy the required
bits, and make sure that we detect when the original files, in the
kernel, gets modified.

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.

We will need it for atomic.h, so move it from the ad-hoc tools/perf/
place to a tools/ subset of the kernel arch/ hierarchy.
Other aches will follow, each in a cset.
