This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
wdparams from short into u_short. If wdp_cylinders is short, it
overflows and cause serious sign extension bug when large IDE HDD is
used. These members are only used for initialization of u_long
variables in both 3.0-current and RELENG_2_2 branch.
I believe this should be in 2.2.

wdreg.h: Delete wd_ctlr macro. PC98 version of wd.c treats it as a
variable.
GENERIC98: Delete ep0 entry. Current ep driver write I/O port 0x100.
This clobbers ICW of i8259, because upper 8bits of address line is not
masked on mother board.
if_fe.c: Merge from revision 1.18 of sys/i386/isa/if_fe.c.
pc98.c: Globalize dmapageport, because SCSI driver use this
variable.
wd82371.c: Yet another merge.
These are 2.2 candidates.

wdp_fixedcyl) gives it directly. wdp_removedcyl is "reserved" except
in ancient ATA-1 drafts and shouldn't be added. This fixes PR 1288.
Changed some fields and comments in struct wdparams to match a less-
ancient ATA draft.
Fixed bit number for `rdy' in status string.

on the hope that the BIOS will have done the right thing already. The
actual interface from the wd driver to the new facility is not
implemented yet (this commit being an attempt at prodding someone else
to do it because looking at the wd driver always confuses the h*** out of me).

sources when the functions are staticalized.
Added idempotency guards to <machine/conf.h>. "ioconf.h" can't be
included when building LKMs so define a wart in bsd.kmod.mk to help
guard against including it.

Allow WD1007 type controllers to work
Support MULTI-BLOCK I/O
Correct delay to use port 0x84, reading the status register

Changed probe message to match SCSI type devices.
enough tests to be considered more stable than current driver.
Lots of work by Bruce, David G., and Guido have gone into this version, and
more is to come in the future.
Support for multiple controllers is in, but doesn't work correctly with
different controllers (IDE AND MFM), but multiple alike controllers appears
to work.
Most of the stray interrupts problems should be fixed, although you will
get a couple 'extra interrupts' when disklabeling and on startup.

This fixes several problems.
It has almost everything that is in the FreeBSD version of Aug 22.
It is missing the bug for 2 drives and still prints <> around the
drive type. It handles BADEND144 less verbosely. It does wdgetctlr()
somewhat differently from NetBSD/FreeBSD.

Fixed printf's to be correct, since Bruce used the old ones. This driver
still prints phantom wd1's on some Maxtor and other IDE drives, I have
a patch I am sending to Bruce for checking.
