Add some support for multiple processors to the pmap module. Still left
...
to do: TLB shootdown code, but that will be much easier to write once
the code to spin up the additional CPUs is working.

Add fine-grained locking, using a locking protocol modeled after the i386
...
UVM pmap's locking protocol, written by Chuck Cranor. Not all of the
support for multiple processors is here yet, but the kernel does run
under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).
This is by no means complete... there are still some possible snares
to take a look at.

page usage manifest constant names.

Keep track of page usage inside the pmap (pvent, l{1,2,3}pt page, "normal").

30188853dc
Increase the efficiency of pmap_l{2,3}pte() somewhat, by allowing the
...
caller to pass an optional 3rd argument, which is the previous level
PTE corresponding the virtual address. If this argument is non-NULL,
the table walk otherwise necessary will be bypassed.

minor cleanups to fit into the NetBSD source tree better (e.g. remove

pull in the Mach3 alpha pmap, as a base for the new pmap module. Modified

from the mach3 versions only as much as necessary to allow the old
NetBSD/Alpha pmap code to compile. THESE WILL NOT WORK AS-IS, and at
minimum will require code to implement reference- and modified-bit
emulation.

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'
