10 * TLB flushing (implemented in arch/cris/mm/tlb.c):
11 *
12 * - flush_tlb() flushes the current mm struct TLBs
13 * - flush_tlb_all() flushes all processes TLBs
14 * - flush_tlb_mm(mm) flushes the specified mm context TLB's
15 * - flush_tlb_page(vma, vmaddr) flushes one page
16 * - flush_tlb_range(mm, start, end) flushes a range of pages
