Modified Files: src/sys/arch/powerpc/oea [netbsd-9]: pmap.c Log Message: Pull up following revision(s) (requested by rin in ticket #938): 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.
