Patch

I was hit by:

Approaching the limit on PV entries, consider increasing either the
vm.pmap.shpgperproc or the vm.pmap.pv_entry_max tunable.

The latter seems to be wrong - vm.pmap.pv_entry_max can't be changed.
The correct name would be vm.pmap.pv_entries.

The code can also be found in sys/arm/arm/pmap-v6.c and might be wrong
there as well.
