Allocalte enough reserved ST-RAM to make the old Xserver work by default.

Closes PR port-atari/41002 from David Ross.

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.

it's the most available network solution for the old Atari machines.

Remove old MD pmap.c files for amiga and atari.
They no longer work due to reorganization of common pmap_motorola.c.

Switch the atari port to the common m68k/m68k/pmap_motorola.c, at last.

Pull the following amiga's pmap changes to atari:
arch/amiga/amiga/amiga_init.c 1.95-1.97, 1.100-1.102
arch/amiga/amiga/pmap.c 1.123, 1.126-1.131, 1.142, 1.145

arch/amiga/include/pmap.h 1.44
arch/amiga/include/pte.h 1.19
arch/amiga/include/vmparam.h 1.35

- change kernel address space layout (i.e. move Sysmap to the end of KVA)
to match other m68k ports, which should be done on yamt-km merge
- rework pmap_zero_page(), pmap_copy_page() and some more other functions
to make them compatible with m68k/pmap_motorola.c
- move pmap_bootstrap() into a separate file to allow using either
the atari pmap.c or the m68k common pmap_motorola.c
- use common m68k include files, pcb.h, pmap_motorola.h, and pte_motorola.h
- misc style and cosmetic changes

Most merge work is done by Tuomo Makinen, and
miscellaneous fixes and cleanups are done by me.

Tested on Falcon with both 68030 and 68060 by Tuomo, and
also tested on TT030 by David Ross on port-atari.

Should be pulled up to netbsd-4 (it requires at least Sysmap changes)
and netbsd-5.

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.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.
