Move the at-shutdown call to resettodr() from cpu_reboot() to kern_reboot().

It's a small step, but it's a step.

Remove unnecessary <sys/malloc.h>.

s/interrput/interrupt/ and s/accesss/access/ in comments.

powerpc: Sprinkle "memory" clobbers on eieio and nearby asm blocks.

Otherwise the compiler may reorder these around loads and stores,
which mostly defeats the purpose.  `asm volatile' just ensures the
instruction isn't _deleted_; it may still move around.

Don't put #ifdefs in prep_initppc().  Instead, let callers specify the
additional BAT-mapped regions they care about.

Fix -fno-common fallout.

Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).

Catchup with rmind-uvmplock merge.

Cleanup includes.  (<net/netisr.h> is handled by softints, not MD anymore,
so this can be nuked).

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Update haad-dm branch to haad-dm-base2.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled.  So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks().  Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown().  No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown().  I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that.  Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Use aprint_* instead of printf, device_t/softc split.

Automatically detect the amount of installed RAM by reading the memory
bank registers from the PCI host bridge. Previously the RAM size was
hardcoded to 64MB.

Also fill out ibm82660reg.h with more definitions from the PowerPC to
PCI Bridge and Memory Controller User's Manual.

Many thanks to Tim Rightnour for helping with this patch.

Add call to pic_init(). Spotted by garbled.

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Change pic_prepivr around a bit.  Handle the default IRQ 7 from the 8259
better, and add a new motivr_get_irq().  The motorola machines require an
actual read from the 8259 for PCI irqs, so in that case, we read the
8259, and then read the IVR to ack the irq.

Move i8259_get_irq() to i8259_common.c for above.

Fix some minor typos in the chip id's for prep residual.

Fix ibmnws and prep to properly initialize the prep ivr depending on if
the machine is motorola, or IBM based.

Tested on a 7043 and an MTX604

More cleanup.  mvmeppc and ibmnws are machines that have a PReP memory
map.  Rather than have each port roll it's own code, use
oea/prep_machdep.c instead.

HAVE_GENERIC_SOFTINTRS is no longer optional.  Delete ifndef'd code from
oea_machdep.c, and move softintr__init() to oea_startup().  Remove
softintr__init from every port's cpu_startup().

More cleanup:
1) Remove lcsplx, strayintr, and foosoft from all the converted ports.
None of this stuff is needed anymore.
2) because lcsplx is just "return spllower", just call spllower from
locore_subr.S instead.
3) Every port (except macppc) had a pretty similar cpu_configure(), so
take the common parts out and make a genppc_cpu_configure() in an attempt
to stop using imask[] outside of intr.c

Initialize prep_intr_reg_off.

Switch over to new pci, isa and interrupt code.

Reorganize the way powerpc port install machine specific headers.
Use <powerpc/oea/bat.h> exclusively and remove <machine/bat.h> and
<powerpc/bat.h>.  Remove unneeded <machine/cpufunc.h>.  To insure
1:1 correspondence of <powerpc/FOO.h> to <machine/FOO.h> include
"../../powerpc/include/Makefile" in "arch/FOO/include/Makefile".
Incororpate <byte_swap.h> into <bswap.h> and then byte_swap.h
