breakage when I tried to merge OpenBSD wi_hostap changes into the
tree. Skibo found the problem and submitted these patches. Thanks!

ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper
to your high-end RAID controller. The interface to the arrays is still
via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly. Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver. Be the first on your block to low-level format unsuspecting
drives that are part of an array!
To enable this, add the 'aacp' device to your kernel config.

timecounter will be used starting at the next second, which is
good enough for sysctl purposes. If better adjustment is needed
the NTP PLL should be used.
ahc_eisa.c:
ahc_pci.c:
Conform to new aic7xxx IRQ API.
Adapt to aic7xxx_freebsd -> aic7xxx_osm changes.
aic7770.c:
Disable card generated interrupt early in our probe for
"extra safety"
Commonize some seeprom code with the PCI side of the driver.
aic7xxx.c:
Correctly initialize a few scratch ram locations during
a sequencer restart. This avoids spurious sequencer ram
parity errors in some configurations.
Include the softc in ahc_update_residual calls. We need it
for some diagnostics in this code path.
Flag a data overrun on an auto-request sense failure as a
CAM_AUTOSENSE_FAIL rather than a CAM_DATA_RUN_ERR.
Force a renegotiation after noticing a parity error. This
covers targets that lose our negotiation settings but don't
bother to give us a unit attention condition. This can happen
if a target fails during a reselection of us during a cable
pull.
Convert some code to using constants.
Fix some typos.
Correct target mode message loop handling. ahc_clear_msg_state
was not clearing the "need to go to message out phase" bit once
our loop was over.
Simplify some abort handling code.
Include tag information in target mode immediate notify events.
When shutting down EISA controllers, don't EISA BIOS settings in
the high portions of scratch ram. This fixes warm boot issues on
some systems.
Save a bit of space by only allocating the SCBs that we can use.
Avoid some code paths in ahc_abort_scbs() if we are currently
acting as a target.
Correctly cleanup stranded SCBs in the card's SCB array. These
are SCBs who's mapping has already been torn down by code that
aborted the SCB by seeing it in another list first.
Add a comment about some potential bus reset issues for target
mode on Twin (EISA only) controllers.
aic7xxx.h:
Cleanup the hardware scb definitions a bit.
Allocate a ful 256 byte scb mapping index. This simplifies
the lookup code since the table covers all possible (and potentially
bogus) values.
Make AHC_DEBUG work again.
aic7xxx.reg:
Updates to hardware SCB definition.
New definitions for target mode fixes.
aic7xxx.seq:
In target mode, initialize SAVED_LUN just after we receive
the identify message. It may be required in the error recovery
path when a normal cdb packet (includes lun) is not sent up to
the host for processing.
Respond to irregular messages during a selection in target mode.
Defer looking for space for a cdb packet until we are about to
enter command phase. We want to be able to handle irregular messages
even if we would otherwise return QUEUE_FULL or BUSY.
Add support for sending Ignore Wide Residue messages as a target.
In the disable disconnect case in target mode, set our transfer
rate correctly once data are availble.
aic7xxx_93cx6.c:
aic7xxx_93cx6.h:
Add the ability to write and erase the seeprom.
aic7xxx_inline.h:
Correct Big Endian handling of large cdb sizes (> 12 bytes).
Adaptec to changes in the calc_residual API.
Correct a target mode bug where we always attempted to service
the input queue even if no progress could be made due to lack
of ATIOs.
aic7xxx_osm.c:
Adaptec to new IRQ mapping API. The new API allows the core
to only enable our IRQ mapping once it is safe (sufficient
initialization) to do so.
Slap bootverbose protection around some diagnostics.
Only attempt DT phases if we are wide.
aic7xxx_osm.h:
Enable big endian support.
Adjust for IRQ API change.
aic7xxx_pci.c:
Be more careful about relying on subvendor 9005 information.
We now only trust it for HBAs. This should allow the driver
to attach to some MBs where the subvendor/device information
does not follow the Adaptec spec.
Only enable interrupts on the card once we are fully setup.
Disable external SCB ram usage on the aic7895. I have not
been able to make it 100% reliable.
Adjust to seeprom routines being properly prefixed with "ahc".
Fix a few bugs in the external SCB ram probing routine. We
need to clear any parity errors we've triggered during the
probe to avoid future, fatal, interrupts.
If we detect an invalid cable combination, pretent there are
no cable at all. This will enable all of the terminators
which is probably the safest configuration we can "guess".

-stable machine via the old-school methods):
Use __FreeBSD_version in preference to __FreeBSD__ >= N where possible.
Define a single variable mythread which is set to curproc or curthread
depending on the OS version (with a comment saying it is a white lie on
4.x since it really is a proc).
NB: __FreeBSD__ is the OS level of the host machine, not the target,
and should never be used, if possible, as __FreeBSD__ >= N.
