tools arch: Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy'
To bring in the change made in this cset: b69656fa7ea2 ("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.
