tools headers: Sync x86's cpufeatures.h
The changes in dd84441a7971 ("x86/speculation: Use IBRS if available before calling into firmware") don't need any kind of special treatment in the current tools/perf/ codebase, so just update the copy to get rid of the perf build warning: BUILD: Doing 'make -j4' parallel build Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h' Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: David Woodhouse <dwmw@amazon.co.uk> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-mzmuxocrf96v922xkerey3ns@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
