s/borad/board/ in comments.

TAB/space/indent cleanup.

Remove unused variables.

Make local functions and variable static.

Fix a wrong comment about mouse buttons, probably derived from Inside X68000.

Add comments why delta Y of mouse input is inverted.

Tidy up callout(9) implementation to handle mouse packets.

- define and use proper macro to specify ticks
- use callout_schedule(9) rather than callout_reset(9) to restart timer

No functional changes.

Sync with HEAD.

Remove dumb middle button emulation code from the ms(4) driver.

Also fix leftover comments (derived from the original Sun's "firm_event"
implementation as seen in sys/dev/sun/ms.c) to sync with reality on x68k.

The current implementation the ms(4) driver just checks whether
two (left/right) buttons are changed in the same packet.
This means it cannot handle a release event correctly if two
buttons pressed simultaneously are released in the different timing.

The middle button emulation should be handled in application layer
as other Xservers do, and I'll import Emulate3Buttons support for the
X68k Xorg based monolithic server.

See my post on port-x68k@ for details:

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.

sync with head.

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")

kill sprintf, fix unused.

Replace tsleep(9)/wakeup(9) with condvar(9) as practice.

Also replace malloc(9) with kmem_alloc(9).
Pevent more possible races.

Tested on both console and Xserver on X68030.

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.

Split device_t/softc, as following its parents zsc(4).  Spotted by isaki@.

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.

cleanup & uniform descriptor owner handling:
* introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals
  the owner of descriptor, according to appropriate sematics
  of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use
  these routines instead of custom code where appropriate
* make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN
  properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP
  in sys_ioctl() & sys_fcntl()
* also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and
  pass the ioctls down to soo_ioctl() as any other ioctl

change discussed on tech-kern@

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

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

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

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.

Add device switch.

Sync kqueue branch with -current.

Catch up to -current.

Remove unused variables.
Correct printf format strings.

Convert all remaining devices.

Add kqueue support (not yet compiled).

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.

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.

Pull up revision 1.9 (requested by itohy):
  Change the implementation of ms(4) polling to use timeout(9)
  software timer, and change the clock interrupt handler not to
  lower interrupt level, in order to eliminate glitches on MPU
  interrupt levels.

Change the implementation of ms(4) polling to use timeout(9) software
interrupt in order to eliminate glitches on MPU interrupt levels.
I don't know whether this is a good solution, but it does work.

Shut up gcc -Wall.

Merged minoura_x68k_bus_h branch.

Sync.

pull up patch to make mouse optional.  Previously it was mandatory
because some mouse-related functions were referenced from other files.
Never committed to trunk because -current uses MI zs driver.  (minoura)

Catch up with a change to the stint interface.

First import of bus_space implementation for x68k port.

Switched to MI zs driver.

Update marc-pcmcia branch from trunk.

Add prototype.

Implement poll(2).

Some cleanup.
- Add missing return-type of function.
- Add missing prototype.
- some gcc -Wall printf warning.
