"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
flexibility in turn; this renderer is 2B stroke (less than 16 pixel
width) font only. If 1B stroke (less than 8 pixel width) font is
ever supported, the font data should be converted into 2B stroke
during font initialization process. 'wsfont_realize()' is to be
proposed in order to have 'CPU and/or accelerator hardware friendly'
format to squeeze maxinum performance.
configured, but after all adapters have been configured. When multiple
adapters are present, only the last configured adapter could be matched
to the boot device slot. The adapter attach routines now check if that
adapter slot matches the boot device slot and saves the softc pointer
for that controller. Then when the disks are configured, dk_establish()
matches the appropriate controller.

PR#5510. It stops the problem on my 5000/200, and two other people have verified that
it fixes the problem on their 5000/200s. I'm waiting for confirmation from the PR
originator before closing the PR.

as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
problem was. A collision between a select and reselect would leave TC
non-zero from the command-out DMA count, which could later be considered
a fatal condition, causing a reboot. The message for that error was
only displayed with DEBUG. Fixed by clearing TC on a reselect. The
non-zero TC detection won't occur in this case, so unconditionally
display the message if it occurs.
Workaround for another problem that resulted from an "Illegal Command"
status from the 53c94 which would get ignored and result in a timeout
(which also reboots the system). Added the missing check for the
illegal command status, and add the workaround of resending the "accept
message" command to the 53c94. Correct fix will be to determine why the
message wasn't sent in the first place. Abort if the resending the
command doesn't work.
Correctly detect a spurious interrupt and ignore it. This was taken
from a newer Mach driver, but did not get the check converted for the
design difference between the current NetBSD driver and the Mach driver.
does a "restore data pointers" when reselected after disconnecting in
the middle of a DMA transfer). The driver needs a different way to know
which script to continue the DMA transfer. The message-in for the "restore
data pointers" loses the original "resume" script, and the driver would
attempt to continue the DMA transfer at the beginning of the current DMA
chunk, rather than at the point the disconnect occured. The result was a
spurious console message, and a trashed filesystem.
