13c94ca56c We've fixed enough bugs that we can actually acquire the scheduler

e12f731db5 On the Alpha, interprocessor interrupts come in at the same priority 
as normal device interrupts.  Because of this, we won't get IPIs while
servicing such interrupts.  This can lead to the following deadlock
scenario as reported by Bill Sommerfeld:
- Process runs on cpu1, but has FP state on cpu0.
- Process executes FP-using insn, causing an FP trap, which causes
  the kernel lock to be acquired.
- At roughly the same time, cpu0 receives a device interrupt, and attempts
  to acquire the kernel lock, which blocks since cpu1 already has it.
- cpu1 sends cpu0 a SYNCH FPU IPI, and waits for cpu0 to release its
  FP state.
- Since cpu0 cannot notice the IPI until it has processed the device
  interrupt, which it cannot do because it cannot acquire the kernel
  lock, we have deadlock.

Solve the problem by adding a spinlock interlock release hook which
checks for pending IPIs and processes them.

Idea from Bill Sommerfeld.

3b15e411a3 add moxa0 at isa entry, marked as experimental 
This was not added also to other config files primarily because the
driver is not properly tested yet; this entry is primarily meant as an example
for those brave souls who want to try moxa.

b6f0a678dd Add support for the m68060-based machines: MVME-172 and MVME-177. 
CPU support taken from a combination of NetBSD/amiga and NetBSD/x68k.

At this time, MVME-172 works but MVME-177 is untested. Since the '177
is otherwise identical to the MVME-167, this should *just work*.

c62d17a551 rationalize the use of b_flags for geteblk() buffers. 
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

fe5b367ce6 In Idle(), only switch to the idle PCB if we're not already running 
on it, and make sure to deactivate the old process's address space,
as this will not otherwise be done by cpu_switch() later once we're
on the idle PCB.

Also, update some comments related to when s0 (i.e. the old process)
is NULL in the context switching code.

fd524293aa Look at opt_m680x0.h to determine whether to use -m68060 compiler option, 
since options M68060 (etc.) is now defopt'ed.
Pointed out by NISHIMURA Takeshi <nsmrtks@comd.nara.sharp.co.jp>.
Use -m68020-60 instead of -m68060 to ensure not to use new instructions.

534a2fa4bb BIOS memory loading messages can be enabled with DEBUG_MEMLOAD. 
Increase VM_PHYSSEG_MAX from 3 to 5 to avoid a panic.  Suggest
increasing VM_PHYSSEG_MAX in the panic message.

dd7146d50b On sun3x, cpu_reboot() calls sunmon_abort() for PROM bug work-around, 
but sunmon_abort() does not restore mon_crp so it causes problems.
Instead, call romVectorPtr->abortEntry (via trap14) from sunmon_halt()
and call it from cpu_reboot().

Now PROM boot command works properly even after halt on my 3/80.
