Add a software PTE bit that indicates that a va -> pa mapping was entered
...
in the physical->virtual list.

Move PTE-related constants here, and make them not depend on a hard-coded
...
page size (i.e. use the one initialized from the HWRPB at boot time).
Do a bit of cleanup while here, rendering old inherited constants obsolete.

Nuke ALPHA_STSIZE and ALPHA_MAX_PTSIZE. Add macros to compute and operate
...
on segments mapped by L1 and L2 PTEs.

Define VPT_INDEX(), which computes the index into the Virtual Page Table
...
of the PTE that maps the specified virtual address.
Thanks to Chris Demetriou and Ross Harvey for clarifying the VPT.

Rename a few macros to better describe what they are:
...
- kvtol1pte() -> l1pte_index()
- vatoste() -> l2pte_index()
- vatopte() -> l3pte_index()

wholesale update from my NetBSD/Alpha source tree. Includes:
...
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.

preliminary Alpha support. note that NOT ALL OF THE MODIFICATIONS TO

THE REST OF THE KERNEL ARE IN THE TREE YET. Also, some of this is
_incredibly_ hack-ish, etc., but it works.
