511223b674 If ALTIVEC is not defined, treat EXC_VEC|EXC_USER exceptions as PGM
exceptions.  [Note that we still can't trap these due to issues in
trap_subr.S which are (yet) fixed]

cd85109523 Make traps even smaller by noticing the checking of privilege mode and
use of curpcb/USPACE is common and move that into the common trap processing.

1a5c0cf685 When not using the OLD pmap, bump kernel KVA space to 512MB (OLD pmap stays

7a12a9737c Revamp how SR(s) are loaded on the user/kernel boundary. We now load all
16 SR registers when transitioning between kernel and user.  Also, don't
reload the kernel SR(s) on every trap but only on traps from user space.
Instead of loading magic SRs for the kernel, load the kernel SRs from the
kernel_pmap_.  This makes trap_subr.S completely ignorant of SR uses and
so they can change with having to change trap_subr.S.  Also note that
since the user and kernel get complete SR sets, user VA space can now be
increased to 4GB if desired.

7c77963b01 Set SR_PRKEY for user pmaps. For the kernel SR(s) set SR_SUKEY|SR_PRKEY.
Note that we never use a PTE PP of 0 or 1 (supervisor protection) so the
"key" is basically unused.  However, use SR_PRKEY for user space is
conceptionally the right thing to do.  Currently the kernel_pmap SR(s) are
ignored but that is going to be fixed shortly.

6fcbf3b943 Don't load the SR registers on a context switch. They get switched from
the user's SR registers to the kernel's SR registers on an exception or
interrupt from user level and restored with the user's SR register when the
exception or interrupt returns back to user level.

2eb3dc82d8 Fix recent bugs seen on Performa 4400 macppc's by
Makoto Fujiwara <makoto@ki.nu> and Manuel Bouyer <bouyer@netbsd.org>.
Help from Allen Briggs, Jason Thorpe, and Matt Thomas.

We need to call cpu_cache_probe() early in boot (machdep.c).
Add 603 info for completeness, and use NBPG not PAGESIZE, as the
latter relies on uvm being setup (cpu_subr.c).
Let uvm_page_recolor() be called before uvm has been set up; just
note the page coloring value (uvm_page.c).

06de426449 SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed

ba482b3950 * On the 601, obliterate all BAT entries when returning from kernel to
userlevel; this is necessary due to the 601, unlike other 6xx, having
  no concept of separated Valid_user vs. Valid_supervisor for BATs.
* When crossing the kernel/userlevel boundary, have platform-provided
  hooks set up the two fixed BAT entries, and possibly additional
  segment registers to redeem the 601's BAT limitations.

Both of the above are only built if the $MACHINE provides these hooks,
sparing others the pain.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

6d536163de Change defaults for kernel compiles. Default all to USETOOLS?=no and have
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
