c2e84d0cde What was missing here is the mapping between our booting SCSI bus number 
and the parent (hba) path from which we booted from. As a temp fix,
we'll only go with the first match to set altbootdev- not additional matches.
The problem was further exacerbated by the fact that cnpoll doesn't seem
to work on serial consoles.

cabecee13c Changes to support fork_kthread(): 
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

addr = map->dm_segs[0].ds_addr & ~PGOFSET;

for inter-processor communications.

Get synchronous fault information separately from asynchronous fault
information. Do the former right after taking a memory fault trap and
store the values in temporary locations within the cpuinfo structure (XXX),
so we can unconditionally clear the sync fault status register after
MMU probe operations. This all is to work around a Hypersparc feature
which could lead to loss of fault information because of the fault
status register getting locked.
