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

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

Some ideas from one posted on tech-net by Jonathan A. Kollasch

Sync with HEAD.

mips_vector_init now takes an argument to specify splsw.
NULL specifies use the default 'std_splsw'

sync with head

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

fix fallout from frame/trapframe merger.

Unify the name of the device property to hold a MAC address - there was
no clear majority for either "mac-addr" vs. "mac-address", but a quick
gallup poll among developers selected the latter.

Add generic support for DMA bounce buffers and real version of
bus_dmatag_subregion.  MALTA uses it for ISADMA.  Make RMIXL use
for creating 32bit and 29bit subregions.

Use mips_page_physload and mips_init_lwp0_uarea.

Merge from matt-nb5-mips64
Merge mips-specific arch files.

- 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.

Kill proc0paddr.  Use lwp0.l_addr instead.

Update to deal with pcb_context being a label_t (this should be a common
routine).

Remove all declarations of physmem from sys/arch.  Add an include of
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)

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

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

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.

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.

merge yamt-idlelwp branch.  asked by core@.  some ports still needs work.

from doc/BRANCHES:

	idle lwp, and some changes depending on it.

	1. separate context switching and thread scheduling.
	   (cf. gmcgarry_ctxsw)
	2. implement idle lwp.
	3. clean up related MD/MI interfaces.
	4. make scheduler(s) modular.

- Further adaptations to MIPS for the yamt-idlelwp branch.
- Make curlwp a register variable on MIPS.

Add a port to the Infineon ADM5120.

Basics: the ADM5120 is a 175 MHz MIPS32 4Kc processor featuring a
6-port ethernet 10/100 switch with Auto MDI/X, a PCI controller,
USB 1.1 controller, UART, watchdog timer, eight GPIO pins, and a
multiport memory controller with both NOR and NAND flash support.
This code supports most of the devices on the ADM5120, including
the 6-port switch (each port attaches as an ethernet, admsw0 through
admsw5), the PCI controller, USB controller, GPIO, watchdog, and
UART.

Remaining work: the port includes no NOR/NAND flash drivers.  No
bootloader is included.  I have only tested the PCI bus driver with
the use of one PCI slot on the RouterBOARD 153.  It is not possible
to exploit the capabilities of the ethernet switch using bridge(4).
I have only netbooted the ADM5120 on the RB153.  Booting other
boards, and booting from flash memory, remains to be done.

Hardware availability: many low-cost routers, including the
RouterBOARD 100 series at RouterBOARD.com, use the Infineon ADM5120
processor.

Credits: Ruslan Ermilov and Vsevolod Lobko ported to the ADM5120,
and they wrote device drivers for the UART, USB controller, and
10/100 switch.  Matt Isaacs brought the port up-to-date with
NetBSD-current, made it compile, and ran it first on the RB153.
I added drivers for the PCI controller, GPIO, and watchdog timer.
I produced the bus attachment for the CompactFlash slot with advice
from Mikrotik technical support and from Matt Thomas.
