Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Significant cleanup and bug fix of root device detection:
* On systems where it's relevant (6600, kn300, kn8ae), check which PCI bus
hierarchy we're looking at.
* Consistently check PCI function numbers (important for quad-channel ATA
controllers).
* Check the channel number (important for ATA and multi-channel SCSI
controllers).
* Check logical unit numbers.
* Use strcasecmp() to check b->protocol; the case is different depending on
the firmware revision.
* Remove b->boot_dev_type check; it's unneeded.
* Remove extraneous unneeded variables.

Not only does this fix a few PRs and multiple long-standing bugs, but the
code is smaller too.

Catch up to ata/ide changes; look for a parent device of wd named "atabus"
instead of "pciide", and check one layer farther up in the device hierarchy
for the scsipidev device.

From Manuel Bouyer, tested by me on a up1500 (identical changes to other
ide-booting code).

Also pass a type argument to comcnattach() and com_kgdb_attach().
comspeed() (and thus cominit()) may need this information.

remove trailing \n in panic(). approved perry.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.

Get the pointer to the driver name early, rather than always dereferencing
the cfdriver pointer.

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.

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.
