Merge thorpej-cfargs2.

Adapt to CFARGS().

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
  actually needed.
- Don't be explicit about what interface attribute is attaching if
  the device only has one.  (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
  situations, making is visibly easier to see when indirect config is
  in play, and allowing for future change in semantics.  (As of now,
  this is just a wrapper around config_match(), but that is an
  implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance.  This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Give config_found() the same variadic arguments treatment as
config_search().  This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls.  Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark hpcsh/bus.h obsolete.

Register null hooks with pmf(9) for now, which is no worse than before
and allows us to test other things.

Turn on display on attachment.  Fixes the scenario when serial console
is used and you reboot (using kloader) with screen turned off.

Update haad-dm branch to haad-dm-base2.

Defining another variable after multiline initializer for a previous
one in the same definition is very confusing visually.  Change order.

Spell "gray scale" and "mono chrome" without the space.

hd64461video_set_display_mode_lcdc - expressing screen widths in hex
hardly helps readbility.  Express them in terms on 640*x or 640/x.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

TRUE -> true, FALSE -> false

future commit will replace use of TRUE and FALSE with true and false.

Refer sc_font.wsfont explicitly instead of playing cast tricks.

Whether hd64461video is console is not is irrelevant to powering it up
on PWR_RESUME.  Drop that bogus test and check whether the screen was
blanked instead to corerctly reflect blanked status across suspends.

HD64461VIDEO options now come from "opt_hd64461video.h".

Use explicit "continue" for busy loop bodies in a couple of places I
missed in the previous commit.

without arguments.  Propagate "static" to function definitions.
Declare local functions static.  Hide acceleration code inside ifdef

jornada 6x0 power mannagement support.
[on/off] button power off LCD and CPU sleeps.

fix hd64461video_get_clut.

Use CONFIG_HOOK_POWERCONTROL_LCD to control turning the LCD on/off
(the _LCDLIGHT hook is apparently meant to control the LCD backlight).

Support for WSDISPLAYIO_PARAM_CONTRAST.

Use CONFIG_HOOK_BRIGHTNESS* to support WSDISPLAYIO_PARAM_BRIGHTNESS.
Use CONFIG_HOOK_POWERCONTROL_LCDLIGHT to turn on/off the LCD in
response to WSDISPLAYIO_SVIDEO.

Implementation of these hooks for Jornada 680 is to follow shortly.

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed.  however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors.  most of
the callers of uvm_useracc() make the above incorrect assumption.  the
rest are all misguided optimizations, which optimize for the case
where an operation will fail.  we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors.  since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

Implement trivial WSDISPLAYIO_SVIDEO that flips DON bit in LCDLDR1.
This only turns off the display in the LCD controller.

TODO: Need to add a platform specific way to turn the screen on and
off as well (e.g. on Jornada 680 this is bit 0 in hd64461 GPIO port B).

In hd64461video_update_videochip_status init depth to supress bogus
-Wuninitialized.

Move the definition of enum hd64461video_display_mode out of the
definition of struct hd64461video_chip.  Makes gcc3 happy.

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.

Replace the access to devsw table and the hard-coded majors with devsw API.

Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

update to -current

You must set 'HPCFB_SWAP_*' if bytes are stored in reverse order, i.e.
little endian like order, however, usage of 'HPCFB_SWAP_*' was widely
misunderstood because it reminded you of 'RI_BSWAP' in raster operation.
Please note that 'RI_BSWAP' indicate that frame buffer byte order is different
from natural order of system while 'HPCFB_REVORDER_*' is independent of
system byte order.

HD64461 frame buffer is big-endian. set HPCFB_SWAP_BYTE.
