This patchset implements use of cacheable versions of memset and
memcpy since when the destination is not cacheable, memset_io
and memcpy_toio are used.

On MPC885, we observe a 7% rate increase on FTP transfer

Christophe Leroy (6):
  powerpc: use memset_io() to clear CPM Muram
  Partially revert "powerpc: Remove duplicate cacheable_memcpy/memzero
  powerpc32: memset(0): use cacheable_memzero
  powerpc32: Merge the new memset() with the old one
  powerpc32: cacheable_memcpy becomes memcpy
  powerpc32: Few optimisations in memcpy
