Remove unnecessary <sys/malloc.h>.

Use vmem(9) rather than extent(9) to manage DVMA mappings.

update from HEAD

Sync with HEAD

remove checks for failure after memory allocation calls that cannot fail:

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Rebase to HEAD as of a few days ago.

this commit was splitted into small chunks to avoid

adapt to recent changes in uvm

converting extent(9) from malloc(9) to kmem(9)
preceding kmem-vmem-pool-uvm patch

Refactoring MD segment related definitions on m68k ports:
- move macro SEGSHIFT, NBSG, and SEGOFFSET from <machine/param.h>
  to <machine/pmap.h> where they should belong
- don't use m68k_round_seg() and m68k_trunc_seg() in sun3 pmap sources
  and instead define and use sun3_round_seg() and sun3_trunc_seg()
  since they are quite pmap implementation dependent

Use lwp_getpcb() on sparc{64} and sun2/3 MD code, clean from struct user usage.

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

- sync with head.
- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.

Sync files of recent sun3 and sun68k merge and intersil7170(4) changes
with HEAD to build sun3 kernel on this branch.

First attempt at bus_space(9) support for sun3 with common sun68k/bus.c:
- make sun3 port use common sun68k files as much as possible
- add temporary options _SUN2_ in std.sun2 until sun3 can share all
  sun68k files (autoconf.c and isr.c are not yet)
- move sun68kvme declaration temporary as well from files.sun68k to files.sun2
- rename and move sun68k_find_prom_map() function to MD sources since it
  can't be shared with sun3
- add bus tag members to struct confargs and initilize them where appropriate

XXX1: MD bus_dma(9) backends are not implemented (yet).
XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

merge ktrace-lwp.

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.

use new apis.

de-__P, remove register, ansify, b* -> mem*, u_int*_t -> uint*_t.

Fix the sync with head I botched.

__KERNEL_RCSID()

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

remove trailing \n in panic().  approved perry.

Don't use rmaps; use extent maps.

Update the kqueue branch to HEAD.

file dvma.c was added on branch nathanw_sa on 2002-10-18 02:40:24 +0000

- vm_offset_t -> vaddr_t, vsize_t, paddr_t
- vm_size_t -> vsize_t
- remove register prefixes
- misc cleanup

Sync with head (for UBC+NFS fixes, mostly).

splimp() -> splvm()

Sync with HEAD.

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.

Fix printf formats in panic messages.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

remove/move more mach vm header files:

	<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

Sync w/ -current.

Add a comment explaining why INTRSAFE isn't needed here.

Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

completely remove Mach VM support.  all that is left is the all the
header files as UVM still uses (most of) these.

Add UVM support

Merge arch/sun3x into arch/sun3

Merged Sun3 and Sun3X kernel sources.

Use the same names as the sun3x (DVMA_MAP_*)

Make DVMA space pointers (void *) like the sun3x.

s/_round_seg/m68k_round_seg/ s/_round_page/m68k_round_page/

s/sun3_/_/ in sun3_(round|trunc)_(page|seg) macros

Changed "machdep.h" to <machine/machdep.h>

Fix copyrights (/s/REGENTS/FOUNDATION/)

Make this compile with -Werror -Wall -Wstrict-prototypes
(finally! yea!)  Also get rid of __BROKEN_INDIRECT_CONFIG

Most  files that were copyright Adam Glass and/or Gordon W. Ross
are now copyright The NetBSD Foundation (rights assigned).

use phys_map for DVMA like the sparc

Need to use set_segmap_allctx() on kernel-space segments.
(Thanks again to David Jones!)

Fix a big "oops" (Many thanks to David Jones!)

New DVMA interface, and various cleanup.
