8ace7abc75 A small splx()/spl0()/soft interrupt related optimisation. If we're
dropping to spl0, use inline code to check if a soft interrupt is
pending instead of taking the hit of a function call to do the check.

c5b6f43634 Define splzs()' to be splserial()' instead of `spl4()', which was
wrong anyway since it blindly set SPL to 4 regardless of the prevailing
level.

7d191ffe77 Revamp the bus_space(9) implementation:
. use a structure for the tag instead of an integer constant,
 . add bus_space_{peek,poke}_N() (and G/C `badaddr()'),

06e91c089b Replace the inline C versions of bus_space_{read,write}_N() with

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*.

4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This
causes gives a primitive form of processor affinity.  Its use in

3f2adcb2b0 Checkpoint of code to add VMEbus slave support using vme_dmamap* and
vme_dmamem*.

This is still a work in progress, but seems to DTRT on mvme167 so far.

TODO:
	. Get VMEbus slave mode going on mvme147. This should be easy.
	. Fix up the A16 slave mappings.
	. Bounce buffer support. (Messy, but pretty much a `must have'.)
	. Figure out how to deal with `location monitor' interrupts
	  within the framework. (Useful for Busnet, among other things.)
	. It would be nice to make use of the VMEchip2's DMA facilities...

889c658b5b Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

463931b3ba Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

	o Most of the bus_dma(9) API.
