[SPARC64]: Add prefetch support. The implementation is optimal for UltraSPARC-III and later. It will work, however suboptimally, on UltraSPARC-II and be treated as a NOP on UltraSPARC-I. It is not worth code patching this thing as the highest cost is the code space, and code patching cannot eliminate that. Signed-off-by: David S. Miller <davem@davemloft.net>
