39254d4d4b Poll console at 50 Hz, not 1024 Hz! (4 tlb and imb coherency ops per poll 
make this exceedingly expensive even on an alpha)  Note: only 3 systypes
still use promcons.

eb3cda883b Probe for the native DraCo (rekeycaped MF-II) keyboard, instead of guessing 
it from the QuickLogic chip version byte.
If found, switch it to non-autorepeat mode (which seems to avoid the race
condition which made my keyboard driver / X server lose state under heavy
interupt load).
If not found, assume an Amiga keyboard on CIA-A.
XXX We should probe for the presence of the CIAs on the DraCo.

18a1481f7a Use NFS_BOOT_DHCP rather than NFS_BOOT_BOOTP. The former is more 
flexible, and the boot blocks use DHCP already(!!!) and it'd be good
for the kernel to be consistent with them.

9bbe89ea3f Garbage-collect the kpt_page stuff; it was basically unused in this 
pmap, and isn't applicable to how dynamically allocated kernel page
tables will work on the Alpha.

faf1155de5 Revamp pv_table management: 
- Make pv_table an array of struct pv_head's, which contain LIST_HEADs
  for the pv_entry's, as well as page attributes (mod, ref, ptpage).
- Use <sys/queue.h> to manipulate pv_entry lists.
- Fix several obvious bugs in pmap_collect_pv().
- Use K0SEG to access pv_page's.

f17bbcfffa Changes necessitated by the fact that all pmaps have their own level 1 
page tables: use curpcb to determine which level 1 map defines the
current VM context, and use that level 1 map when mapping and unmapping
the PROM.

c4e7c88520 Step 1 of the Grand Alpha Pmap Rototill: 
- Clean up pmap_bootstrap() some, and make a slight change to how the
  PROM mappings are saved.
- Give each pmap its own level 1 page table, rather than sharing a global
  level 1 page table.  This will eventually allow for Very Large user
  address spaces.
- Keep a list of all pmaps, so that when kernel level 2 page tables are
  allocated, all level 1 tables may be updated.
- Add a couple of functions for allocating and freeing page table pages.
- Add a few comments about ASN allocation.

5d56ce57ba Several changes related to all pmaps having their own level 1 
page table:
- Update the current hwpcb pointer in the SWITCH_CONTEXT macro, so that
  we know it's always correct.
- Optimize cpu_switch(): if we're switching to ourselves, skip the
  actual context swap.
- Clean up some comments and remove some code rendered obsolete by
  the fact that address spaces are now selected by switching to a
  new level 1 page table.
