| * Cache flushing: |
| * |
| * - flush_cache_all() flushes entire cache |
| * - flush_cache_mm(mm) flushes the specified mm context's cache lines |
| * - flush_cache_dup mm(mm) handles cache flushing when forking |
| * - flush_cache_page(mm, vmaddr, pfn) flushes a single page |
| * - flush_cache_range(vma, start, end) flushes a range of pages |
| * |
| * - flush_dcache_page(pg) flushes(wback&invalidates) a page for dcache |
| * - flush_icache_range(start, end) flushes(invalidates) a range for icache |
| * - flush_icache_page(vma, pg) flushes(invalidates) a page for icache |
| * |
| * Caches are indexed (effectively) by physical address on SH-2, so |
| * we don't need them. |
