      This only causes these perf files to be rebuilt:
      
        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 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
        Warning: Kernel ABI header at 'tools/arch/x86/include/asm/disabled-features.h' differs from latest version at 'arch/x86/include/asm/disabled-features.h'

      tools headers UAPI: Sync linux/kvm.h with the kernel sources · eee51fe3
      Arnaldo Carvalho de Melo authored
      To pick the changes in:
      
        1b870fa5 ("kvm: stats: tell userspace which values are boolean")
      
      That just rebuilds perf, as these patches don't add any new KVM ioctl to
      be harvested for the the 'perf trace' ioctl syscall argument
      beautifiers.
      
      This is also by now used by tools/testing/selftests/kvm/, a simple test
      build succeeded.
      
      This silences this perf build warning:
      
        Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
