Log Message:
Pull up following revision(s) (requested by rin in ticket #1732):
sys/arch/powerpc/oea/pmap.c: revision 1.96
Stop returning while PMAP_LOCK() (= KERNEL_LOCK(1, NULL)) is held.
Kernel freeze with heavy load is significantly mitigated (fixed?),
in which I could not even enter DDB from console.
XXX
There is still inconsistency in usage of two PVO pools.
I will send-pr later.
XXX
