    tools headers: Update the copy of x86's mem{cpy,set}_64.S used in 'perf bench' · 31d2e6b5
    Arnaldo Carvalho de Melo authored
    We also continue with SYM_TYPED_FUNC_START() in util/include/linux/linkage.h
    and with an exception in tools/perf/check_headers.sh's diff check 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:
    
      69d4c0d3 ("entry, kasan, x86: Disallow overriding mem*() functions")
    
    That addresses these perf tools build warning:
    
      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
