* 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
* - flush_cache_sigtramp(vaddr) flushes the signal trampoline
