if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible. Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.
buffer had to be left on the head of the queue for [bufq]disksort()
to sort against. This isn't right for devices that can support multiple
active i/o's, and only the fd driver did it. "Fixing" this in rev.1.36
of ufs_disksubr.c broke the fd driver in much the same way as rev.1.52
of <sys/buf.h> broke it (see rev.1.119).

Make two digit years specified on the command line represent
the century that the computer currently resides. So 99 means
1999 this year, but 2099 next year.

the black hole device is present and some other target/lun is enabled
for target mode.
Handle the IGNORE WIDE RESIDUE message. This support has not been tested.
Checkpoint work on handling ABORT, BUS DEVICE RESET, TERMINATE I/O PROCESS,

Fix a few problems with tagged command handling in target mode.
Wait until the sync offset counter falls to 0 before changing phase
after a data-in transfer completes as the DMA logic seems to indicate
transfer complete as soon as our last REQ is issued.
Simplify some of the target mode message handling code in the sequencer.
'Black Hole' device uses this feature to schedule itself against any
target or lun attached to a controller that receives an unwanted request
from an initiator instead of having an instance per potential target/lun
request.
Use the wildcard entries to simplify wildcard async callback storage.
Don't announce devices twice to peripheral drivers. The devices will
be announced as soon as the AC_PATH_REGISTERED event is registered by
the peripheral driver, so no manaul push of this event is required.

data and sense information for target mode devices for which no other
peripheral driver is attached. This simplifies the task of dealing with
luns that are not otherwise enabled for target mode if the controller
does not have firmware that automatically deals with this case (e.g.
the aic7xxx driver).
