switch all ports to use uvm_init.c:uvm_md_init()

uvm_setpagesize() is now subsumed within this funciton.

Remove katelib.h and references to it.

{Read,Write}{Word,Byte} macros are provided in the files that still use
them. Someone(tm) should convert them to bus_space(9)

Rebase to HEAD as of a few days ago.

Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed.  Default cortex to pmap_needs_fixup = 1.  But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.

Move the standard definitions of the {UND,IRQ,FIQ,ABT}_STACK_SIZE to
<arm32/machdep.h>
Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.

Fix more -fno-common fallout.
Move more variables to common locations.

More setttb() -> cpu_setttb() for readability & consistency.  Missing instances
pointed out by tsutsui@ & nonaka@, thanks.

- 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.

Explicitly include <sys/exec_aout.h> for ZMAGIC etc.

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.

Fix EB7500ATX kernel to build again, mainly catching up on 6+ months of
changes elsewhere in the kernel:
* kernel_l1pt is now a global in pmap
* wdc no longer has dma/udma caps without the relevant options, however,
  rside doesn't support dma/udma so don't set the options.
* also fix a device_t/softc split issue.

Perhaps I should add the kernel to the default build list for acorn32, to
avoid any other breakage. Although as the only person probably even
running NetBSD on an EB7500ATX system I'm not sure it's worthwhile.

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.

Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

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.

First part of support for the eb7500atx board from simtec:
http://www.simtec.co.uk/products/EB7500ATX/

also available with RISC-OS as a RiscStation:
http://www.riscstation.co.uk/html/products.html

This is basic bootstrap with support for ide and networking, currently only
tested with booting from ABLE, and not RISC-OS.

I would have placed it into evbarm, but iomd doesn't appear to use the same
interrupt files as evbarm.  I'll check it into here for now, until iomd
uses the common interrupt code.
