Cleanup unnecessary semicolons from the kernel.

Found with devel/coccinelle.

Use callout(9) instead of timeout(9).

Migrate the olpt(4) driver to si_drv1 instead of using dev2unit().

Approved by: nyan

Replace all calls to minor() with dev2unit().

After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

Since DELAY() was moved, most <machine/clock.h> #includes have been
unnecessary.

- Move lptreg.h into pc98/cbus and rename to olptreg.h.
- Remove ifdef pc98.

- Remove ifdef PC98.
- Reduce diffs from i386.

Device megapatch 4/6:

Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

Device megapatch 1/6:

Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

Replace evil abuse of geteblk() with malloc(9).

Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

More low-hanging fruit: kill caddr_t in calls to wakeup(9) / [mt]sleep(9).

Fix typos, mostly s/ an / a / where appropriate and a few s/an/and/
Add FreeBSD Id tag where missing.

KSE changes for olpt driver

Reviewed by: julian, bde, jhb

Removed PLIP support.

Convert the olpt driver to using new-bus stuff.

Send the remains (such as I have located) of "block major numbers" to
the bit-bucket.

Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue. Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue. An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

Remove unneeded #include <machine/clock.h>

Update of isa drivers using compatability shims to use COMPAT_ISA_DRIVER().

Submitted by: haro@tk.kubota.co.jp (Munehiro Matsuda)

Fixed header file path (machine/lpt.h -> dev/ppbus/lptio.h).

Separate the struct bio related stuff out of <sys/buf.h> into
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

Fixed to support old parallel interface.

Submitted by: chi@bd.mbn.or.jp (Chiharu Shibata)

- Fixed warnings.
- Removed unnecessary include files.

Remove five now unused fields from struct cdevsw. They should never
have been there in the first place. A GENERIC kernel shrinks almost 1k.

Add a slightly different safetybelt under nostop for tty drivers.

Add some missing FreeBSD tags

Remove NBPF conditionality of bpf calls in most of our network drivers.

This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

$Id$ -> $FreeBSD$

Add PHK's make_dev() into more places where DEVFS used to be
hooked in directly.

PC98 changes checked by: Takahashi Yoshihiro <nyan@FreeBSD.org>

Rename bpfilter to bpf.

New parallel port support for PC98. Old PC98s which have
uni-directional parallel port should use olpt driver instead of lpt
driver.
