  arm64: Add MOPS implementations of memset(), = memcpy() and memmove()

  Enable the use of MOPS = implementations of memset, memcpy and memmove within
  the = kernel. Fix pre-ifunc resolution uses of these = functions.

And = what happens if the compiler inserts calls to these functions = prior
to IFUNC = resolution?

Probably as well as if the = compiler inserted calls to memset/memcpy/memmove before ifunc resolution = on amd64 given it has had it for these functions since = 2018.
