Modified files:
sys/ia64/ia64 pmap.c
Log:
* Don't use critical_enter/critical_exit when accessing the VHPT - its
pointless and would be inadequate for SMP systems. We will rely on the
VM system's locks to serialise this for now.
* Change pmap_remove() so that if the range being removed is larger than
the number of pages mapped by the pmap, we iterate over the currently
mapped pages instead of over the virtual address range. This should
make a difference when removing large virtual address ranges from an
address space.
