860b0688ac defopt "options SUN4*", put #define for each of SUN4, SUN4C, SUN4M and SUN4U 
into opt_arch_sparc.h and include this wherever they are used.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Reviewed by Jason.

cbe144f269 copy tlb_flush*() #defines here, but rename them tlb_flush*_real(). this 
allows for tlb_flush*() to be defined differently if MULTIPROCESSOR.

55044638aa Remove pmap_kenter_pgs(). It was never really adopted by 
anything, and the interface itself wasn't as flexible as
callers would have probably liked.

7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

b19b1fc269 Each process (i.e. each `pmap') needs a region table for each CPU. 
Implement this by making the fields `pm_reg_ptp' and `pm_reg_ptp_pa'
pointers to an array of `ncpu' region table pointers and corresponding
physical addresses.

This is a somewhat unfortunate side effect of having the per-CPU data
addressable by the same virtual address on each CPU.

f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports. 
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

3ebbe095e0 Change the pmap_extract() interface to: 
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful, 
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.

9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.

8abe0d6b1c Adjust for the new "reaper" kernel thread: do not free the vmspace and 
u-area in machine-dependent code.  Instead, call exit2() to schedule
the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).
