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.

c9c7976f7f 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.

5dbb062210 Make ofw_console a low priority console device, so that uart will be
preferred in all cases, even if the "remote" bit is not set.

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.

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.

761f89f9d8 Implement the ALT_BREAK_TO_DEBUGGER option for the ofw console. This is very
handy if the machine is on another floor. A minor issue with this is that
these functions are also used by the debugger, so its possible to break into
the debugger from the debugger.

984e265523 Change ofwcons to use the output-device property from the firmware for the
name of the device that it creates.  Update /etc/ttys accordingly.

An alias is created for the old name so that old /etc/ttys will continue to
work, but due to aliases being implemented as symlinks in devfs you cannot
login as root when using the alias device.

a121cb6a7f Create the ofwcons device at SI_SUB_CONFIGURE instead of SI_SUB_DRIVERS,
after configure() has run.  Only create the device if ofwcons is the
highest priority console.  Make a dev alias with the same name as the
firmware output-device property.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

47a1c91514 Move the make_dev call from the cn_probe to a sysinit that runs at
SI_SUB_DRIVERS.  cnprobe is too early.

cbecdd5743 1. Lower the poll timeout for the ofw console driver from hz / 50 to hz / 4.
This gives a bit of a sluggish console, but it prevents the console from
   getting stuck if we poll too fast, as well as other badness on certain
   machines.
2. Fix a test for != 0 that should have been > 0.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

ports later on.

This includes the basic MI interface routines as well as a console driver.
The MD code is kept in the MD directories.
