The cache functions lock out interrupts for long periods; this patch reduces the impact when operating on large address ranges. In such cases it will: - Invalidate the entire cache rather than individual addresses. - Do nothing when flushing the operand cache in write-through mode. - When flushing the operand cache in write-back mdoe, index the search for matching addresses on the cache entires instead of the addresses to flush Note: sh2a__flush_purge_region was only invalidating the operand cache, this adds flush.
