Remove unnecessary <sys/malloc.h>.

follow the steps of Andrew Doran (ad) commit and fix more s/loose/lose/ typos.
also s/beyound/beyond/ and few others along the way, mainly in comments.

Sync with HEAD.  77 conflicts resolved - all of them $NetBSD$

convert some spaces into new lines and tabs to make the gcc 6
indent checker happy.

update from HEAD

Update copyright notice for Ludd (remove clause 3 & 4).

KNF. Remove extra spaces. No functional change.

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

Add d_discard to all struct bdevsw instances I could find.

I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Cleanups includes.  Change <machine/XXX.h> to <sys/XXX.h>
Remove unneeded includes.

Rototill the vax code.  Switch to devicet/PRIV_ALLOC.  Cleanup vax autoconf
code.  Move to prototype definitions.  staticfy, constify, avoid casting.
Use device_* accessors.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

- Back out the biodone() changes.
- Eliminate B_ERROR (from HEAD).

Sync with HEAD.

Sync with HEAD.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

Fix caddr_t fallout.

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

merge ktrace-lwp.

Sync with HEAD. Here we go again...

- change the way to specify a bufq strategy.  (by string rather than by number)
- rather than embedding bufq_state in driver softc,
  have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
  from sys/bufq.h to sys/bufq_impl.h.
  (is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c.  (not tested)

Sync with HEAD.

move buffer queue related stuffs from buf.h to their own header, bufq.h.

Fix the sync with head I botched.

Sync with HEAD.

Adapt to new world order.

Vax GENERIC compiles.

Sync with HEAD

Work around gcc 2.95.3's inability to detect that 'ck' will be set
in rounds 129 and 130 through the loop.  Will be noted in doc/HACKS,
and should be reviewed when gcc 3.3.2 is ready for vax.

Catch up to -current

merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

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

Catch up to -current.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Write support for TU58 tapes written.

Add checksum calculation, busy-wait loops for receive packets and use
correct interrupt levels (spl7). Reading tapes now work reliable.

splimp -> splbio.

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.

A foolish consistency; most parts of the kernel use bp->b_data, so
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Fix a bug in disksort_*() which caused non-optimal ordering when multiple
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.

Revamp the VAX interrupt handling code.  Make it compatible with all the
other ports.  Clean up some things.

remove volatile from softc.  cleanup interrupt initialization.

Update for sys/buf.h/disksort_*() changes.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

Added prototypes to everything. Made all files compile with -Wall.

Add a #ifdef TUDEBUG around a printf statement.

Console TU58 device driver for 11/750 added.
It cannot write tapes yes, but reading works OK.
