19 * This pair is called at time of munmap/exit to flush cache and TLB entries
20 * for mappings being torn down.
21 * 1) cache-flush part -implemented via tlb_start_vma( ) for VIPT aliasing D$
22 * 2) tlb-flush part - implemted via tlb_end_vma( ) flushes the TLB range
24 * Note, read http://lkml.org/lkml/2004/1/15/6
