d154229cf2 Don't define PAGE_SIZE, etc. in terms of NBPG, rather use the same 
logic as used by <machine/param.h> to define constant PAGE_SIZE if
possible.

Also define the minimum and maximum PAGE_SIZE that might appear in
any given configuration (4K and 8K, respectively).

b418a6a59d Some PROMs get really uneasy if the prom_reboot() function is called

So don't do it; try to halt the other CPUs only when an actual `halt'
is requested.

My guess in this case is that the PROM does not expect its original boot
CPU to call prom_cpustop(0), or possibly treats it as the equivalent of
a prom_halt() which is then called again by some other CPU. In any case,
the result is garbage.

88f08d9ac1 - add a new message tag for level15 software NMI, and switch ddb to use this 
rather than the level13 software intr xpmsg area.  now DDB IPI's don't lock
the xpmsg_lock and we avoid recursion and more.
- don't actually use cpuinfo.msg.lock yet, xpmsg_lock suffices.
- reread the pending register on mbus hypersparc cpus to avoid bugs in the
h/w that cause IPI's to be missed.

4bb41ae2f2 Rework how KERNOBJDIR functions; now it's always determined with 
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile.  Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.
