These changes made the tools/arch/x86/include/ headers to drift from its kernel origins:910448bbed("perf/x86/amd/uncore: Rename cpufeatures macro for cache counters")5442c26995("x86/cpufeature, kvm/svm: Rename (shorten) the new "virtualized VMSAVE/VMLOAD" CPUID flag")cba4671af7("x86/mm: Disable PCID on 32-bit kernels") Which was detected while building perf: make: Entering directory '/home/acme/git/linux/tools/perf' BUILD: Doing 'make -j4' parallel build 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' Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h' This sync causes just these perf object 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 the changes in the above changesets don't entail any need for change in the above 'perf bench' files.
