The following patch set provides optimized versions of
memcpy/mempcpy/memmove/memset/bzero for Sparc versions M7 (and later).
Support for recognizing M7 is also provided.
An assembly version of memmove for ultra1+ is provided.

Jose E. Marchesi (1):
  sparc: support the ADP hw capability.

Jose E. Marchesi (2):
  sparc: assembly version of memmove for ultra1+

Patrick McGehearty (3):
  sparc: M7 optimized memcpy/mempcpy/memmove

Patrick McGehearty (4):
  sparc: M7 optimized memset/bzero
