(atapi_action, case XPT_SCSI_IO): Enable DMA only for READ and WRITE commands
as some combinations of chipset, controller and target do not behave
correctly when DMA is enabled for other commands.
PR: kern/103602
(atapi_cb): Fix test for the presence of sense data. An incorrect condition
was being tested, which would result in a system hang in some configurations.
PR: kern/112119
(reinit_bus): When the ATAPI bus is reset, do not schedule an automated
CAM rescan if the ATAPI device entries have not changed.
The ATAPI bus may be reset for a variety of reasons, including any time an
ATAPI request times out. It is not necessary to rescan at the CAM level
in such a case, unless a device has appeared or disappeared, or has
otherwise changed.

MFC revs. 1.49 and 1.50:
(atapi_action): Improve error reporting by removing ATA_R_QUIET flag
from ATAPI requests. If CAM debugging is enabled, also mark ATAPI
requests with ATA_R_DEBUG flag.
(atapi_cb): Report ATAPI timeouts to the CAM layer.
Fix incorrect debugging traces in the presence of ATAPI errors.
PR: kern/103602
(ata_completed): When REQUEST SENSE is automatically issued after a failed
ATAPI request, do not clear the ATA_R_DEBUG flag. This allows a request
marked as requiring debug traces to produce these traces also during
the completion of the autosense processing.
Fix a typo in ata-queue.c

CF devices are ATA not ATAPI.
Add support for the ALI/ULI M5288 AHCI part
Busmaster DMA address fix in VIA 6421 case
Add support for a few more Serverworks and lookalikes chips
If current_heads or current_sectors in the disk cap page are zero, dont try to use the current_ geometry. This avoids a panic with BIOS'n that sets these to zero.
Format mask lacks one bit.

Dont poll for ATA_IDLE on a detached channel in suspend.
Add support for the Serverworks HT1000 chip.
Finally fix support for the newer MCP51/MCP55 nVidia chipsets.
Add support for the ICH8 and ESB2 chips, also add a few other missing ICH7 partsUpdate JMicron support to also work with chips where the PATA and SATA
parts are on individual PCI functions.
Add support for VIA 8237A.
Add support for AHCI on the VIA VT8251.
Dont call free on non-alloc'd items.
Only use the channel in the request given to ata_completed if its
still present.
Only look for ICRC and CORR errors on ATA devices not ATAPI.
Get rid of all the "long long"/"maxint" casting around in printf's.
On all our platforms intmax == int64_t so simply using %j to print
int64_t's is safe all over, and doesn't pullute the code.
Update atapi-fd to support direct devices such as disks.
ATAUSB will need to hook into the delayed boot identify to have
interrupts running, so externalize it.
Add USB modes.

Keep the parent device (in this case the channel) around in ata_request,
so we dont panic device removal or failure.
Clean up ata_fail_requests to prevent the queue munging to fail.
Fix ata_reinit so it does things in the right order to prevent panic's.
Lock the channel so master/slave setups wont trash during reinit.
Work around the deadlock that occours when ATA waits for the taskqueue
to call back for completition and something else is holding the taskqueue
waiting for ATA to return data.
This should clear up the "semaphore timeout !! DANGER Will Robinson !!"
in most situations, and log "taskqueue timeout - completing request directly"
instead, with a delayed "WARNING - freeing taskqueue zombie request" when
the taskqueue finally calls us back with the now stale request.
(It would have been nice if there was a way to remove a scheduled item from
the taskqueue finally calls us back with the now stale request.

Dont clear the delayed flag before we are acutally finished.

The RIAD5 code is not complete, it does not use nor maintain the parity, so

When breaking up a large request into smaller ones for the strategy
routine, create all the child bio objects before starting the
requests, rather than starting them as created. This closes a race
whereby some number of child operations could complete before the
rest were ever created, and prematurely freeing the parent bio.

to initialize the buffer array in ata_raid_attach() by removing the
initializer. There's no memset(?) in the kernel. Instead, assign
'\0' to the first element. The buffer array holds strings only, so
this is functionally equivalent.
