cd955b850f Bits 0 (MMU Enable) and 1 (Fault inhibit) are common among the implementations

Also add the swift `store allocate' bit.

47df99b02a __HAVE_NWSCONS seems to mean, "If this port uses pckbc(4), it also uses 
sys/dev/pckbc/files.pckbc."  This is true of sparc, so define __HAVE_NWSCONS,
and remove the code in pckbc_machdep_cnattach() that was conditional on its
not being defined and that is no longer needed (since with __HAVE_NWSCONS,
pckbc_cnattach() will call pckbd_cnattach() itself if necessary).

089abdad44 Rearrange process exit path to avoid need to free resources from different 
process context ('reaper').

From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
  as FPU state), and is the last potentially blocking operation;
  all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
  by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
  for both 'process' and 'lwp' exit

uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.

MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.

g/c now unneeded routines and variables, including the reaper kernel thread

119a91826a If compiling for JavaStations, modify kernal VA layout to not conflict 
with the PROM. From Valeriy E. Ushakov. This is a hack, but as long as
we don't have a way to arrange for a proper VA layout on this machines
(i.e. beyound the PROM) it is needed.
