tools headers: Update the copy of x86's memcpy_64.S used in 'perf bench'
We also need to add SYM_TYPED_FUNC_START() to util/include/linux/linkage.h and update tools/perf/check_headers.sh to ignore the include cfi_types.h line when checking if the kernel original files drifted from the copies we carry. This is to get the changes from: ccace936eec7b805 ("x86: Add types to indirectly called assembly functions") Addressing these tools/perf build warnings: Warning: Kernel ABI header at 'tools/arch/x86/lib/memcpy_64.S' differs from latest version at 'arch/x86/lib/memcpy_64.S' diff -u tools/arch/x86/lib/memcpy_64.S arch/x86/lib/memcpy_64.S Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Kees Cook <keescook@chromium.org> Cc: Sami Tolvanen <samitolvanen@google.com> Link: https://lore.kernel.org/lkml/Y1f3VRIec9EBgX6F@kernel.org/ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
