    tools arch x86: Sync asm/cpufeatures.h with the kernel sources · 40f1c039
    Arnaldo Carvalho de Melo authored
    To pick up the changes from:
    
      b4dd4f6e ("x86/vmware: Add a header file for hypercall definitions")
      f36cf386 ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
      be261ffc ("x86: Remove X86_FEATURE_MFENCE_RDTSC")
      018ebca8 ("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.
