-/* 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_icache_range(start, end) flush a range of instructions
- * - flush_dcache_page(pg) flushes(wback&invalidates) a page for dcache
- *
- * MIPS specific flush operations:
- *
- * - flush_cache_sigtramp() flush signal trampoline
- * - flush_icache_all() flush the entire instruction cache
- * - flush_data_cache_page() flushes a page from the data cache
