sbus specific stuff for eni155s sbus atm card.

machines with IOMMUs(?).

Turn on disconnect/reselect by default on targets 4-7 on the premise that
...
tape devices normally are set to one of these targets. Tape devices should
be allowed to disconnect for the SCSI bus to operate acceptably.

First go at a TCX framebuffer driver. This version does enough to

load and store colour lookup tables
blank the screen / put monitor in power-saving mode
make X11 run on it in `cgthree' emulation.

bootpath detection: some (newer?) v2 prom versions use actual device address,

Allow DIAGNOSTIC kernels a FLUSHWIN trap in order to record stack traces

(currently used by the nullfs filesystem code, noted by der mouse).

Bound the buffer cache to 1/2 of kernel virtual memory, so machines with

lots of core don't run out of core (takes care of PR#2506).

Turn on RB_ASKNAME if a `swap generic' kernel was not able to determine

the boot device. Also, call boot device hooks for all types of kernel
configurations.

Use `ic_*' cacheinfo fields, and in the split-I&D case, derive `c_linesize[l2]'
...
from from the corresponding `ic_*' and `dc_*' values. This is not perfect,
but it makes SS4s and SS5s run until we have proper per-cpu cache handling.

Use `ic_*' cacheinfo fields, and in the split-I&D case, derive `c_linesize[l2]'
...
from from the corresponding `ic_*' and `dc_*' values. This is not perfect,
but it makes SS4s and SS5s run until we have proper per-cpu cache handling.
Use the `cache-physical?' property to determine the value of `vactype'
on sun4m's. If absent, set vactype to VAC_WRITETHROUGH (XXX) else VAC_NONE.
Print simpler sun4m CPU identifier on attach.

Avoid the "features enable" bit on ESP100A's; apperently this is a source

of trouble on many machines (from Krister Walfridsson; PR#2537).

Fix two cases of handling stale page table information:
...
1. when reading the referenced/modified bits the TLB entry must be flushed
before reading the in-core version.
2. when wrapping up an entire segment in pmap_page_protect(), flush the PTPs
from the TLB to prevent a table-walking operation to pick up stale - or
possibly bogus - PTEs.
(hopefully I'll get a few of my hairs back now..)

mmu_pagein() is only useful on sun4/sun4c. For now, keep a `mmu_pagein4m()'

within `#ifdef DEBUG' for monitoring.
Push user windows to stack in pmap_extract() if we need to switch contexts.
