fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

38703ed315 Convert iic to use make_dev() rather than cdevsw_add(). This stops the
annoying 'iic is usurping iic's cdevsw' type messages.  (Yes, there are
other ways to fix cdevsw_add(), but that is a doomed api)

fb45ca12a7 Fix: WARNING: "iic" is usurping "iic"'s cdevsw[] - the DEV_DRIVER_MODULE()

d6a0e38a1b Remove five now unused fields from struct cdevsw. They should never
have been there in the first place.  A GENERIC kernel shrinks almost 1k.

Add a slightly different safetybelt under nostop for tty drivers.

46783fb897 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

15317dd875 Alter the behavior of sys/kern/subr_bus.c:device_print_child()
- device_print_child() either lets the BUS_PRINT_CHILD
	  method produce the entire device announcement message or
	  it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing
	  as bus_generic_print_child(), use bus_generic_print_child()
	- Use device_get_nameunit() instead of both
	  device_get_name() and device_get_unit()
	- All BUS_PRINT_CHILD methods return the number of
	  characters output.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

I4b and vinum not changed.  Patches emailed to authors.  LINT
probably broken until they catch up.

4e2f199e0c This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

        The d_reset field was not removed, although it is never used.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.

Vinum and i4b not modified, patches emailed to respective authors.

46eede0058 Continue where Julian left off in July 1998:
Virtualize bdevsw[] from cdevsw.  bdevsw() is now an (inline)
        function.

        Join CDEV_MODULE and BDEV_MODULE to DEV_MODULE (please pay attention
        to the order of the cmaj/bmaj arguments!)

        Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE
        (ditto!)

(Next step will be to convert all bdev dev_t's to cdev dev_t's
before they get to do any damage^H^H^H^H^H^Hwork in the kernel.)
