Modified files:
sys/sys bus.h
sys/kern device_if.m subr_bus.c
Log:
Implement device_quiesce. This method means 'you are about to be
unloaded, cleanup, or return ebusy of that's inconvenient.' The
default module hanlder for newbus will now call this when we get a
MOD_QUIESCE event, but in the future may call this at other times.
This shouldn't change any actual behavior until drivers start to use it.
