tools headers cpufeatures: Sync with the kernel sources
To pick the changes from: 690a757d610e50c2 ("kvm: x86: Add CPUID support for Intel AMX") 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 Cc: Jing Liu <jing2.liu@intel.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Link: https://lore.kernel.org/lkml/YflQCEO9FRLeTmlB@kernel.org/ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
