f3732fd15b Second half of the dev_t cleanup.
The big lines are:
	NODEV -> NULL
	NOUDEV -> NODEV
	udev_t -> dev_t
	udev2dev() -> findcdev()

Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

dc08ffec87 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.

a8d43c90af Add a "int fd" argument to VOP_OPEN() which in the future will
contain the filedescriptor number on opens from userland.

The index is used rather than a "struct file *" since it conveys a bit
more information, which may be useful to in particular fdescfs and /dev/fd/*

For now pass -1 all over the place.

7ac40f5f59 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.

ba8aae1baf Now works again and as a module and with devfs.
Used the bpf & tun drivers as examples as to what is necessary for devfs.

a62615e59b Implement vop_std{get|put}pages() and add them to the default vop[].
Un-copy&paste all the VOP_{GET|PUT}PAGES() functions which do nothing but
the default.

fb919e4d5a Undo part of the tangle of having sys/lock.h and sys/mutex.h included in
other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

OK'ed by:	bde (with reservations)

d6a0e38a1b 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

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

I4b and vinum not changed.  Patches emailed to authors.  LINT
probably broken until they catch up.

4e2f199e0c This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

        The d_reset field was not removed, although it is never used.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.

Vinum and i4b not modified, patches emailed to respective authors.

7b91328a39 Support KLD. We register and unregister two modules. "coda" (the vfs)
via VFS_SET(), and "codadev" for the cdevsw entry.  From kldstat -v:
