40dd98a3bd 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.

dfd1f7fd50 Do the dreaded s/dev_t/struct cdev */ 
Bump __FreeBSD_version accordingly.

ba3920e2a2 Machine generated patch which changes linedisc calls from accessing 
linesw[] directly to using the ttyld...() functions

The ttyld...() functions ar inline so there is no performance hit.

b59eec9a5a There is no need to explicitly call ttwakeup() and ttwwakeup() after 
ttyclose() has been called.  It's already been done once by ttyclose,
and probably once by the line-discipline too.

ad925439e0 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.

fcf7e634fb Device megapatch 3/6: 
Add missing D_TTY flags to various drivers.

Complete asserts that dev_t's passed to ttyread(), ttywrite(),
ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty
pointer.

Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default
cdevsw methods for D_TTY drivers and remove the explicit initializations
in various drivers cdevsw structures.

df397dedea 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.

24775302eb - Clean up global data. 
- Force dcons to be the high-level console after dcons_crom
	has been attached.
- Add a tunable to be the high-level console.

c96f6e4f1d Add dumb console driver and related bits. 
dcons(4): very simple console and gdb port driver
dcons_crom(4): FireWire attachment
dconschat(8): User interface to dcons

Tested with: i386, i386-PAE, and sparc64.
