[PATCH 0/5] Tune and tweak memmove/wordcopy code for Powerpc

The following series copies, tunes and tweaks the implementation of memove and
wordcopy functions for powerpc, in particular power7.

The "Call memcpy when appropriate" optimization (2/5) could apply to other
architectures generically; but I can not make any claims to how
much improvement (if any) it provides for those archs.


Will Schmidt (5):
      [Powerpc] tune/optimize memmove/wordcopy. Populate files.
      [Powerpc] tune/optimize memmove/wordcopy. Call memcpy when appropriate.
      [Powerpc] tune/optimize memmove/wordcopy. Add helper macro to call MERGE
      [Powerpc] tune/optimize memmove/wordcopy. Convert switch to if-then-else
      [Powerpc] tune/optimize memmove/wordcopy. preload srcp values
