Arnaldo Carvalho de Melo 8f21164321 tools headers x86 cpufeatures: Sync with the kernel sources to pick BHI mitigation changes

To pick the changes from:

  95a6ccbdc7199a14 ("x86/bhi: Mitigate KVM by default")
  ec9404e40e8f3642 ("x86/bhi: Add BHI mitigation knob")
  be482ff9500999f5 ("x86/bhi: Enumerate Branch History Injection (BHI) bug")
  0f4a837615ff925b ("x86/bhi: Define SPEC_CTRL_BHI_DIS_S")
  7390db8aea0d64e9 ("x86/bhi: Add support for clearing branch history at syscall entry")

This causes these perf files to be rebuilt and brings some X86_FEATURE
that will be used when updating the copies of
tools/arch/x86/lib/mem{cpy,set}_64.S with the kernel sources:

      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
