c292276dcf Change our DVMA map from the last 16MB to the last 1MB because that is 
the only part that is visible to VME masters, and is adequate space.
This allows the "si" driver (on VME) to use DMA transfers.

cc1b4e4724 In pmap_bootstrap_copyprom, copy only the last PTE from the PROM's 
DVMA segment (for the page reserved by the PROM).  If we copy all
the mappings, pmap_enter_kernel may complain about finding valid
PTEs that are not recorded in our PV lists.  Make pmap_remove_pte
do something reasonable if it finds a PTE for a managed page that
has not been recorded in the PV lists.  (Plus other minor stuff).

58126a3b29 Separate pmap_activate() from _pmap_switch(), so the latter can remain 
equivalent to what locore.s:cpu_switch does with in-line assembly when
PMAP_DEBUG is not defined.  Also do splimp/splx in pmap_activate.

0e5cf40b1f Always include pmap_pinit(), since it is a defined pmap interface 
function (thought, we might revisit that later).  Just call pmap_pinit()
in pmap_create(), instead of inlining what pmap_pinit() does.

Also, g/c a TAILQ_FIRST() macro that is now defined in <sys/queue.h>

f106a637c6 Implement a "kernel-only" context for processes that have not 
touched any user-space address recently.  This is efficient
for things that stay in the kernel for a while, waking up
to handle some I/O then going back to sleep (i.e. nfsd).
If and when such a process returns to user-mode, it will
fault and be given a real context at that time.

This also makes context switch faster, because all we need
to do there for the MMU is slam the context register.
