        syssrc/sys/arch/sh5/sh5: locore_subr.S

Log Message:
Performance tweak to the copy_page/zero_page asm code.

Allocate/Prefetch one cache-line ahead of the one we're about to deal with.

This reduces the chances of the cpu stalling while waiting for the cache
to flush a dirty line in order to satisfy the Allocate/Prefetch request.
