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.

pmap.old.<whatever>. To see the history, look at the corresponding

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'
program and works a lot like the NetBSD/sparc boot blocks.
