a2f214a443 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.

6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

dc13176aec No need to keep global pointers to the initial kernel level 2 and level 3 
page tables.  Also, rename Lev1map to kernel_lev1map.

95bdb660ed Simple screen attribute handling for wscons. 
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

0624060713 Rework PCI interrupt mapping on the EB164 systype. Rather than computing 
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register.  The previous scheme did not work properly on
AlphaPC 164SXs.  Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

4665241bf8 Simplify the direct-mapped DMA case somewhat by adding a window base

be purged when all of the old legacy consoles have gone away.

b217194508 Fix the semantics (and the comment describing them) of pmap_update(). This 
function is intended to process any deferred pmap operations, and is not
meant as a general means of flushing the TLB.  Since this pmap module does
not defer any operations, make pmap_update() do nothing.

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.
