Introduce null console. This pseudo device acts as a normal console with the
...
exception that it discards any output, and is useful for booting the kernel
on headless boxes.

Make 'minor(dev) == 1' a device that isn't affected by TIOCCONS.
...
For /dev/constty so that you can grab kernel messages when logged in
on the 'console'.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
...
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V

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

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.

Use back the 'u'&037 form - since it's CTRL-u, it's more readable that way

Use \007 instead of symbolic constant, since that's what is more often used.

don't cdevvp() if a vnode for the dev already exists. Note that that's
...
conceptually icky; you end up ref'ing a 'real' vnode, and hence perhaps
tying down a file system; should be able to reference a 'fake' one,
but i doesn't appear save to cdevvp() if vnode for same dev is already
around... also, mark vfinddev()s XXX (for later).
