tools headers x86 cpufeatures: Sync with the kernel sources
To pick the changes from:
f24ef0093dd8cf60 ("KVM: x86: Advertise MOVRS CPUID to userspace")
f49ecf5e110ab0ed ("x86/cpufeature: Replace X86_FEATURE_SYSENTER32 with X86_FEATURE_SYSFAST32")
db5e82496492b489 ("KVM: SVM: Virtualize and advertise support for ERAPS")
This causes these perf files to be rebuilt and brings some X86_FEATURE
that may be used by:
CC /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
CC /tmp/build/perf/bench/mem-memset-x86-64-asm.o
And addresses this perf build warning:
Warning: Kernel ABI header differences:
diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h
Please see tools/include/uapi/README for further details.
