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.

8e1f1df080 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.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

Not objected in:	-arch, -current

3f99f14bf1 OK, I messed up /dev/console with what I had hoped would be compat
code.  Convert remaining console drivers and hope for the best.

Also some minor style cleanups.

5ff9e59f71 Fix a signedness problem in zstty_cncheckc(): when no character is ready,
-1 should be returned, but it was assigned to an uint8_t (which is
extended to an int to form the return value), causing 255 to be returned
instead.

d42ee4e410 Note that MAJOR_AUTO is now the default if d_maj is not initialized. This
is more robust and prevents the hijacking of /dev/console for the typical
mistake.

Remove unneeded MAJOR_AUTO uses, it is only needed explicitly now if the
driver source has cross-branch compatibility to old releases.

182a9f7455 Make nokqfilter() return the correct return value.
Ditch the D_KQFILTER flag which was used to prevent calling NULL pointers.

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.

263444cfbf Change the console interface to pass a "struct consdev *" instead of a
dev_t to the method functions.

The dev_t can still be found at struct consdev *->cn_dev.

Add a void *cn_arg element to struct consdev which the drivers can use
for retrieving their softc.

a42a7e2f13 Set the termios speed based on the tty speed. This allows consoles to work at
speeds other than TTYDEF_SPEED.

6bfa8a2ef2 Split this into bus specific front end(s), so that it can be used by ppc.
This abstracts out all the differences I could see between the netbsd
sparc64 and macppc zs drivers.   In particular the offsets of the csr and
data registers are different, so we use a separate bus handle for each and
use bus_space_subregion to add the bus specific offsets.

777cc88b9d - This damnable chip only has 1 status register for both ports, so the bit
positions for the status bits of port a and port b are different.  To
  avoid needing to know which channel the interrupt handler is working on,
  shift the status bits for port a into the port b bit positions, and always
  check the port b status bits.  This fixes using port b, which I neglected
  to test before.
- Remember to update the channel's tty structure from the passed in termios
  in the param routine.
- Minor style.

75db2b5e27 Add a driver for the Zilog 8530 dual uart found in Ultra 1s and Ultra 2s.
With a 1 byte transmit fifo, 3 byte receive fifo, and wierd multiplexed I/O
designed for a Z80 cpu, this chip redefines suckage.

Based on the openbsd and netbsd drivers.  Only really works as a console,
modem support is not complete since I can't test it.
