[PATCH] ppc32: export cacheable_memcpy()
Add declaration and cacheable_memcpy(). I'll be needing this function in new 4xx EMAC driver I'm going to submit to netdev soon. IMHO, the better place for the declaration would be asm-powerpc/string.h, unfortunately, ppc64 doesn't have this function, so asm-ppc/system.h is the next best place.
