[PATCH 0/4] powerpc32: use cacheable alternatives of memcpy and memset

From: Christophe Leroy
Date: Tue May 12 2015 - 09:33:16 EST

This patchset implements use of cacheable versions of memset and
memcpy when the len is greater than the cacheline size and the
destination is in RAM.

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

Christophe Leroy (4):
Partially revert "powerpc: Remove duplicate cacheable_memcpy/memzero
powerpc32: swap r4 and r5 in cacheable_memzero
powerpc32: memset(0): use cacheable_memzero
powerpc32: memcpy: use cacheable_memcpy
