tools headers cpufeatures: Sync with the kernel sources
To pick the changes from: d45476d983240937 ("x86/speculation: Rename RETPOLINE_AMD to RETPOLINE_LFENCE") Its just a comment fixup. 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: Borislav Petkov <bp@suse.de> Cc: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lore.kernel.org/lkml/YiyiHatGaJQM7l/Y@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
