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.

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.

PR/6311: By me... There was a bug unloading the dmamap:
...
addr = map->dm_segs[0].ds_addr & ~PGOFSET;
len = map->dm_segs[0].ds_len;
len = ((addr & PGOFSET) + len + PGOFSET) & ~PGOFSET;
addr &= ~PGOFSET;
Notice that the & ~PGOFSET in the first line should be gone. This fixes
the newfs large disk panic.
