From 40f1c039c7c6de913ee04eac585102e2fce7f6f7 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 20 Sep 2019 15:00:49 -0300 Subject: [PATCH] tools arch x86: Sync asm/cpufeatures.h with the kernel sources To pick up the changes from: b4dd4f6e3648 ("x86/vmware: Add a header file for hypercall definitions") f36cf386e3fe ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS") be261ffce6f1 ("x86: Remove X86_FEATURE_MFENCE_RDTSC") 018ebca8bd70 ("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.
