9e8e4c5bdc I was wrong, sh4 does have a VAC. 
change vmapbuf()/vmunmapbuf() back to using pmap_enter()/pmap_remove().

17d06a7ad7 use pmap_k* in vmapbuf() and vunmapbuf() since there's no VAC on this platform. 
in vunmapbuf(), call pmap_*remove() explicitly since uvm_km_free_wakeup()
will soon no longer do it for us.

c495131fe3 Move _insque()/_remque() to libkern. Once remaining uses would 
be converted to <sys/queue.h> macros, _insque()/_remque() would be eliminated
altogether.

0756145b0f fix a ldtlb handling bug: 
- set to PTE{H,L,A} and call LDTLB must do atomically.
 - never call LDTLB when it's unnecessary.

Broken kernel oocasionally causes cpu reset when /etc/security is called.
Now fix this problem.

b1c2276feb Correct a simple bug in the recent commit (pmap.c:1.19) by thopej. 
I guess he indents to prepare a temporary variable for saving the next
pointer of a list element, but he seems to forget to substitute the
pointer for the variable.  This often causes my dreamcast panic.

cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

d7e12660a3 Work around the problem that causes kern/12554. Basically, 
there are some pathological cases that cause pmap_page_protect()
to be called on a wired page to revoke all mappings.  We
need to skip mappings that are actually wired to prevent Bad
things from happening later.

THIS IS JUST A WORK-AROUND.  We need to prevent the pathological
behavior from happening in UVM to begin with.  But it's unclear
what the right solution is there, right now.

1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.
