Instead of cc, use CC.
This allows cross-compile.

Also, there is no point in mapping more than the 'visual' area for vga memory.
this will save kvm space on large memory display cards.

We have enough floating point problems without multimedia in the kernel.

paddr_t should be protected with _LOCORE

Fix up rd in those cases.
|
|
|
|
Also, and more importantly, applying the same mask to rs2 and rd is bad ju-ju for the F?TO? instructions.

This maps the region with mapiodev().
|
|
calling another driver to turn on it's enables properly.
For now wi_obio will mapiodev the keywest enable region.

the setjmp/longjmp hack in place for VAX_BTYP_4[689]. This solves
the /boot problem which prevented automatic boots from happening
when the timer ran down.

need to verify that kernel exception code deals with this properly.
|

at least mostly useable.

for paranoia's sake (don't want to break sparc32 while hacking on it).
Real work by art.

It attempts to follow proper powerpc assembler syntax
and makes the disassembly much more readable.

All this ugliness makes it harder to debug the code.
