[PATCH 05/10] tools arch x86: Sync asm/cpufeatures.h with the kernel sources

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

To pick up the changes from:

  b4dd4f6e3648 ("x86/vmware: Add a header file for hypercall definitions")
  f36cf386e3fe ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
  be261ffce6f1 ("x86: Remove X86_FEATURE_MFENCE_RDTSC")
  018ebca8bd70 ("x86/cpufeatures: Enable a new AVX512 CPU feature")

These don't cause any changes in tooling, just silences this perf build
warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
  diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h

To clarify, updating those files cause these bits of tools/perf to rebuild:

  CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
  CC       /tmp/build/perf/bench/mem-memset-x86-64-asm.o
  INSTALL  GTK UI
  LD       /tmp/build/perf/bench/perf-in.o

Those use just:

  $ grep FEATURE tools/arch/x86/lib/mem*.S
  tools/arch/x86/lib/memcpy_64.S:	ALTERNATIVE_2 "jmp memcpy_orig", "", X86_FEATURE_REP_GOOD, \
  tools/arch/x86/lib/memcpy_64.S:		      "jmp memcpy_erms", X86_FEATURE_ERMS
  tools/arch/x86/lib/memset_64.S:	ALTERNATIVE_2 "jmp memset_orig", "", X86_FEATURE_REP_GOOD, \
  tools/arch/x86/lib/memset_64.S:		      "jmp memset_erms", X86_FEATURE_ERMS
  $

I.e. none of the feature defines added/removed by the patches above.
