To do list (not in any particular order).
o Improve pmap_zero_page and pmap_copy_page. Speed and flushing.
o Move the RO and WIRED attribute from the pte to the pv table.
This saves four instructions in the tlb miss handler.
InWork: Have a test version. The system hangs after a while. Not solved yet.
Also, is it worth the effort to remove 4 instr. in TLB-miss handler?
o Boot. Standalone boot program instead of booting the kernel directly?
o sigsetjmp/siglongjmp missing....
o Add more videomodes to pccons driver. 50kHz and 64kHz monitors?
InWork: This seems to be hard. Need more info on the chip.
o Find out why bitmap load to S3-928 flashes screen.
Know why (enable linear mode). Need S3 info.
o Can we have 32 double registers?
Lots of other things.....
