Presently The SH-4 cache flushing code uses flush_cache_4096() for most of the real flushing work, which breaks down to a fixed 4096 unroll and increment. Not only is this sub-optimal for larger page sizes, it's also uncovered a bug in sh4_flush_dcache_page() when large page sizes are used and we have no cache aliases -- resulting in only a part of the page's D-cache lines being written back.
