mjacob 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.

thorpej 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.

Makes the whole concept useless. This is for default printouts. If you
can build a debug kernel, you know what version you have. This was under
the concept of 'RAS' so that hapless users could tell you microversion
things. But I guess this isn't the right way according to our local
Jesuits. Oh, well. I'll think up something different and hopefully
less objectionable. And yes, NetBSD isn't linux. The developers seem
to be equally bad tempered, but linux is more successful.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
