[PATCH] ppc32: export cacheable_memcpy()

[PATCH] ppc32: export cacheable_memcpy()

[Eugene Surovegin]

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.
