Hmm, the patch makes kernel boot into single user
(i.e. now it can mount nfsroot via dhcp),
but it hangs during /etc/rc script.

There is no assertion in cpu_idle(9) and
I can't get ddb(4) prompt even on serial console,
so maybe it's a different problem. (spl race?)

BTW, a bit off topic, but I notice the following possible issue:

- arm/include/arm32/psl.h still has obsolete spllowersoftclock()

- arm/arm32/intr.c:dosoftintr() could call splx(),
  but splx() also calls dosoftintr().
  Isn't it better to have a spllower()-like function
  which doesn't call dosoftintr()?
  (as macppc/macppc/extintr.c:do_pending_int() does)
