SVN rev 211217 on 2010-08-12 10:09:28Z by jchandra
Implement pmap changes suggested by alc@:
1. Move dirty bit emulation code that is duplicted for kernel and user
in trap.c to a function pmap_emulate_modified() in pmap.c.
2. While doing dirty bit emulation, it is not necessary to update the
TLB entry on all CPUs using smp_rendezvous(), we can just update the
TLB entry on the current CPU, and let the other CPUs update their TLB
entry lazily if they get an exception.
