Add struct pmap_limits and pm_{min,max}addr from uvm/pmap/map.h and use it to
store avail_start, avail_end, virtual_start, and virtual_end.
Remove iospace and let emips just bump pmap_limits.virtual_start to get the
VA space it needs.
pmap_segtab.c is almost identical to uvm/pmap/pmap_segtab.c now.  It won't
be long until we switch to the uvm/pmap one.

Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework

Adjust things to the new world order.

Deal with various changes with avail_end and avail_start, etc.

Merge from matt-nb5-mips64
Merge mips-specific arch files.

Fixup (all but mipsco) to deal the new realities in mipsland.

Use bus_dmamem_common.

Sync w/ -current. 34 merge conflicts to follow.

Also fix build.

vm_page: put TAILQ_ENTRY into a union with LIST_ENTRY, so we can use both.

Cast to char*, not void* before doing pointer arithmetic.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

sync with head - hopefully this will work

Mising -> Mixing

merge yamt-uio_vmspace branch.

- use vmspace rather than proc or lwp where appropriate.
  the latter is more natural to specify an address space.
  (and less likely to be abused for random purposes.)
- fix a swdmover race.

_dm_proc -> _dm_vmspace.

adapt the rest of MD code.

merge ktrace-lwp.

bus_dmamem_map: honour BUS_DMA_NOWAIT.  noted by Manuel Bouyer.
bus_space_map: always do NOWAIT allocation as it used to be before yamt-km.

we have too many copies!

Sync with HEAD.

merge yamt-km branch.
- don't use managed mappings/backing objects for wired memory allocations.
  save some resources like pv_entry.  also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.

sync with head.  xen and whitespace.  xen part is not finished.

Add a dm_maxsegsz public member to bus_dmamap_t.  This allows a user of the API
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create).  dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.

Don't deref a NULL struct lwp *. This shouldn't happen, but...

sync with head.

use new apis.

Sync with HEAD.

Misc cleanup:
- ANSI function decls
- remove __P()
- u_intNN_t -> uintNN_t
- remove register decls
- bcopy -> memcpy, strcpy
- bzero -> memset
- bcmp -> memcmp
- use malloc(9) with M_ZERO
- some KNF
etc.

bus_dmamap_load_mbuf(): Skip zero-length mbufs.

Fix the sync with head I botched.

__KERNEL_RCSID()

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

TAB/space cleanup.

Use PAGE_SIZE rather than NBPG.

catch up with -current.

curlwp back to curproc; curproc is the correct type here.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

catch up with -current on kqueue branch

Catch up to -current.

move initialization of the "struct pglist" returned by uvm_pglistalloc()
from the calling code into uvm_pglistalloc() itself for consistency
and easier error handling

Sync kqueue branch with -current.

file bus.c was added on branch nathanw_sa on 2002-06-20 03:40:16 +0000

Merge the thorpej-mips-cache branch onto the trunk.  This is an
overhaul of how caches are handled for NetBSD's MIPS ports.

Don't forget to actually fill in _dm_proc.

Make the newsmips port compile with the thorpej-mips-cache branch.

Catch up with -current.

Update the kqueue branch to HEAD.

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.

Catch up to -current.

replace vm_page_t with struct vm_page *.

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.

Make this stuff compile with -wstrict-prototpes -wmissing-prototypes.
More use of prototypes inside includes should be done.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

file bus.c was added on branch thorpej_scsipi on 2000-11-20 20:17:27 +0000

Move APbus dependent unmapped DMA address stuff from bus.c to apbus.c
Support DMA mapping table with NEWSMIPS_DMAMAP_MAPTBL flag for APbus
(MAPTBL is not tested yet).

Remove a '^G'.

Bus I/O and DMA access macros/routines.
