Add support for the power button on the PowerBook 160/180.

Apple Sound Chip audio support for 68k Macintoshoes.

This provies a sound device and support for wsbell(4).

Add MAC68K_MEMSIZE option to hard-code memory size in MB, instead of
that given by Booter. Work around Booter bug by which max memory is
restricted to 255MB.

Add genfb(4) driver for mac68k grfbus.
1, 2, 4, 8, 15, and 32 color-depths are supported.

ANSI colors on console are functional for depth >= 4.

Graphic applications based on wsfb API should work, provided
they can correctly handle fbi_fboffset and your color depth.

wsfb driver of Xorg 1.20 and mlterm-fb (framebuffer version of
x11/mlterm) work fine for depth == 1 || depth >= 8.

For depth == 8 (256 colors), graphic applications require
colormap callback, which is currently supported for some
internal graphic adapters, and only Civic (found on Quadra
AV series) was tested. Register definition and its usage are
taken from Linux. You can easily support other adapters if
Linux supports that.

Have fun, and any problem reports are welcomed!

Refactor the 68040 writeback() from each m68k port's trap handler into a
shared copy: m68040_writeback(). It is essentially a copy of the Atari
version, with some minor cosmetic tweaks and one small performance optimization
from the mvme68k port.

Tested by rjs@ on a Quadra 950. (Thanks!)

Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

add a special rule to build m68k/fpu.c to avoid passing -msoft-float.
fixes GCC 6 kernel builds that use this file.

Merge copy-and-pasted fpu_probe() function (to share it among more m68k ports).
Tested on TT030, Sun3/80, and X68030.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

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.

Rather than attaching fpu as a usual device during cpu_configure(9),
initialize it explicitly in identifycpu() (before cpu_configure(9))
because after yamt-idlelwp merge savectx() is called before
cpu_configure(9) and it requires fputype initialized properly,
otherwise a kernel fails in savectx() if a machine doesn't have an FPU.
