description:
soft_splvm() - "block" SPLBIO, SPLNET, and SPLTTY in addition to SPLIMP
and the soft interrupts.  Probably doesn't matter for an all OFW kernel,
since all devices are polling, but done for correctness.

soft_splsoftnet() - make sure to block softclock, as well.  While
you're in the network code at splsoftnet(), you don't want a soft
clock interrupt tripping some network-related timeout and reentering
the network code.
