jdolecek e0cc03a09b 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

gehenna 77a6b82b27 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.

thorpej 32ff91814a Add "xor2", "xor3", and "xor4" function names, which perform an
XOR on 2, 3, and 4 input streams, respectively.

thorpej add44d0f41 Fix a signed/unsigned botch that broke an error recovery path.
(I could have sworn I fixed this bug over a week ago...)

thorpej 5d06c0e812 dmover(9) -- an interface to hardware-assisted data movers. This allows
clients to use a hardware-assisted data mover to clear a region of memory,
fill a region of memory with a specific value, copy a region of memory,
and perform simple boolean operations such as XOR on multiple regions
of memory.

Included here is a software back-end which can serve as an example of
how to write a back-end (and also provides a fall-back in case hardware
for a given function is not available), as well as a dmoverio(4) pseudo-
device which provides access to dmover(9) to userland via a message
passing interface.

dmover(9) is still a work-in-progress -- a few minor changes to the
interface are expected.
