a23660903d Add code to configure cpus, ioapics and interrupt wiring using ACPI. 
Shuffle some code around so that this an exist as a method next
to mpbios, both creating the same data structures. If both are
defined, try ACPI first.

d2dfe3f39a Define acpi_md_callback. It retrieves interrupt routing info if the MP 
BIOS wasn't already used for that (currently won't happen; ACPI gets
to try first if configured).

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.

0098f248ba PCI fixup code for the O2. Tested with a range of 32 and 64-bit network 
cards, but not much else.  Seems to work fairly well, though.

c21021e6fb Improve the interrupt code somewhat by having callers of xxx_intr_establish 
pass in an interrupt handle (which is currently to the CRIME interrupt the
device is attached to) so the interrupt handlers know which device was the
one looking for attention.

While here, fix up PCI interrupt routing for both the on-board devices and
the PCI slots -- even though there is only one PCI slot in the chasis, the
hardware can accomodate up to three and provides an interrupt mapping for
all the PCI interrupt pins for both the internal SCSI & PCI slot and the
two "extra" slots.
