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

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

Remove "#ifdef RAMDISK_HOOKS" block, RB_DFLTROOT boot flag is obsolete long ago.

Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).
Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:

 https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

Worth to pullup to both netbsd-8 and netbsd-9.

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.

merge to -current.

Add PXA25x based Zaurus SL-C700/750/760/860 support.

All porting work was done by TOYOKURA Atsushi, with
several minor adjustments for integration by me and nonaka@.

His SL-C700 first running NetBSD/zaurus was demonstrated on
NetBSD booth at Open Source Canference 2011 Tokyo/Fall:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-tokyofall

Note GENERIC kernel works on SL-C750/760/860 (and C1000/3x00) but for now
SL-C700 requires its own kernel with special KERNEL_BASE_PHYS address
due to zbsdmod.o loader restriction (probably caused its small 32MB RAM).

Reorganlization zlcd(4) and ztp(4) device attachments from nonaka@:
 - ztp depends on zssp so attach ztp at zssp rather than pxaip
 - split LCD backlight controls from zlcd(4) into new lcdctl device
   to share it among forthcoming SL-C7x0 variants

Kernel load address can be changed now.

SL-C700 has PXA250 step B instead of PXA250 step A.

Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

dependant -> dependent

support FFUARTCONSOLE.

As md(4) no longer has "needs-count" there is no "md.h" anymore.
Remove the inclusion of this file.

Acorn32 now always builds load_memory_disc_from_floppy().  This should
not be a problem as all configs have md(4).

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.

Remove all declarations of physmem from sys/arch.  Add an include of

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.

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.

Patch by Slava Semushin <slava.semushin@gmail.com>

Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.
