Browse source 
To bring in the change made in this cset:

  b69656fa7e ("x86/uaccess: Fix up the fixup")

Silencing this perf 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

No changes in the tooling using this, that was just to ease some objtool
return checking.
