Modified Files:
        src/sys/uvm/pmap: pmap_tlb.c pmap_tlb.h

Log Message:
Allow this to handle H/W tlbs.  Some ARM allow for a cheap way to flush all
entries using an ASID from the TLB.  Add support for taking advantage of it.
Most ARMs don't have an easy way to find out what's in the TLB so make
record_asids can just say all ASIDs are in use.  Fix some off by 1 errors.
