perf bench: Update the copies of x86's mem{cpy,set}_64.S
And update linux/linkage.h, which requires in turn that we make these files switch from ENTRY()/ENDPROC() to SYM_FUNC_START()/SYM_FUNC_END(): tools/perf/arch/arm64/tests/regs_load.S tools/perf/arch/arm/tests/regs_load.S tools/perf/arch/powerpc/tests/regs_load.S tools/perf/arch/x86/tests/regs_load.S We also need to switch SYM_FUNC_START_LOCAL() to SYM_FUNC_START() for the functions used directly by 'perf bench', and update tools/perf/check_headers.sh to ignore those changes when checking if the kernel original files drifted from the copies we carry. This is to get the changes from: 6dcc5627f6ae ("x86/asm: Change all ENTRY+ENDPROC to SYM_FUNC_*") ef1e03152cb0 ("x86/asm: Make some functions local") e9b9d020c487 ("x86/asm: Annotate aliases") And address 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 Warning: Kernel ABI header at 'tools/arch/x86/lib/memset_64.S' differs from latest version at 'arch/x86/lib/memset_64.S' diff -u tools/arch/x86/lib/memset_64.S arch/x86/lib/memset_64.S Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Jiri Slaby <jslaby@suse.cz> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-tay3l8x8k11p7y3qcpqh9qh5@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
