of the ICU in clock_attach.

  stealing code from the sun3 port).

sommerfe 9fefd40478 In 16-bit mode, mov %ax,%bx is interpreted as mov %eax,%ebx; this
breaks zero-extension of the 16-bit memory size return from the BIOS.
on at least one system, the trash left in the upper half of %eax
causes the kernel to crash during VM system initialization when it
thinks it has on the order of 2**31 bytes of memory to play with.

We now *say* mov %eax,%ebx, but *mean* mov %ax,%bx..

scottr 1c0a3c8ce7 Several more changes to move us toward MI-ness:
- Use more consistent and portable types in the softc.
 - Map registers using an array of bus_size_t offsets, and set up the
   mapping in the attach code (thanks to Jason Thorpe for suggesting
   this!).
 - Disable the ae-specific watchdog, which is no longer necessary in
   the general case.

Still remaining:  split out functions used to copy data to/from the
card, and retain a way to have a local driver name with the MI code.

	* Improved scninfo program to dump driver internal information.
	  implemented counters for parity err, framing err, break
	* Delays changes until transmitter idle to avoid "glitches"
	* Cleaned up scn_softc member names
	* Untested support for sc26c92 (I don't yet have any to test with);
	  + Will use alternate rate tables (include 115.2kbps and 230.4kbps)
	  + Will raise FIFO rx interrupt threshold and watchdog timer
	    at higher rates.
	  + Unknown (to me) how fast pc532 MC145406 driver chips can go

	NOTE: It seems like it may be a BAD idea to use a sc26c92 as
	a console port for now; the PROM doesn't know to reset the
	chip back to scn2692 mode!!

pk eb71a02a7f Re-write of CPU/MMU detection code.
Use a table driven classification based on CPU and MMU implementation/version
fields. Each CPU class or module defines a collection of routines that
implement CPU or MMU specific operations that can collect detailed setup
information.

All information is collected in a `cpu_softc' structure provided by the
auto-configuration code. However, in the interest of SMP support this
structure is located at a fixed virtual address identified by the
symbol `cpuinfo'. The `boot' CPU currently uses the the physical page(s) at
address 0x2000 for its cpuinfo. Consequently, the fixed virtual address
will be `KERNBASE+0x2000'.

The cache flush routines for several systems (sun4/4c vs. sun4m;
virtual vs. physical tags) have been factored out. Function pointers
to an appropriate set are located in `cpuinfo'. The former global
`cacheinfo' structure is now also a part of `cpuinfo'. Because of the
fixed virtual address of `cpuinfo' no extra performance penalties
are incurred by this move. In multi-architecture kernels, there's
no longer the need for run-time `cputyp' tests in this part of the system.

pk 8d2c03c810 Replace `cputyp' run-time tests by inserting multiple branches and NOPing
some at startup depending on architecture.

Use `get_faultstatus' field in `cpuinfo' (initialized in cpu.c) to branch
to CPU/MMU specific fault status reading stubs on memory fault traps.

Remove code top map the Interrupt Enable register on sun4/sun4c. Its VA
has moved to a high location and is now mapped in autoconf.c after
pmap has initialized. Note: this renders NMIs during bootstrap() fatal
(maybe loading %tbr should be deferred).

gwr a4e5a18b63 Add pmap_bootstrap_setprom() with sets the PROM level-A tables to
allow the PROM monitor to see mappings in kernel space.  This also
fixes a problem with exiting to the monitor with the stack pointer
set to some place in kernel space.  Also fix NUM_KERN_PTES, and
change get_pte() so it works on any virtual address.
