structures in softc teardown.

hasseen_isadev so this will be less noisy when conflicts do exist.
Also eliminate redundant warnings about conflicts.

o For bt and aha only probe the one I/O range if a specific I/O is specified
in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

is a work-around from an LRAM access bug on the 940UA. In a future
microcode revision, the high 16bits of residual information will be moved
to a safe location and we'll return to 32bit residuals. Since we only
allow 64KB I/O, 16bits is enough.
queued.
Perform dma segment setup outside of splcam protection as this can take
some time and the protection is not necessary.
Inline a function.
Clean up some whitespace.
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.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine. This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in. It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.
PCI and EISA front ends will show up as soon as I get my hands on
the cards. There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)
Thanks to AdvanSys for releasing this code under a suitable copyright.
