Subject: [PATCH 5.10 147/148] tools arch: Update arch/x86/lib/mem{cpy,set}_64.S copies used in perf bench mem memcpy - again

From: Arnaldo Carvalho de Melo <acme@...hat.com>

commit fb24e308b6310541e70d11a3f19dc40742974b95 upstream.

To bring in the change made in this cset:

 5e21a3ecad1500e3 ("x86/alternative: Merge include files")

This just silences these perf tools build warnings, no change in the tools:

  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
