  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
