thorpej 1268cc5d6c If we got an xfer from our backlog queue, don't allow sleeping; we're in
interrupt context.

XXX This is fixed properly in the thorpej_scsipi branch, but that won't
be ready for 1.5, I don't think.

thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.

thorpej 4399060ec9 - Perform all necessary bus_dmamap_sync() operations.
- Greatly simplify allocation and DMA mapping of the mailbox and ccbs.
- Be more robust against resource shortage errors, and report errors better.

thorpej 8abe76d2f0 Add offset and length parameters to bus_dmamap_sync(), used for specifiying
partial syncs of a DMA mapping.

thorpej a7c5c1ef3c Add dm_mapsize to bus_dmamap_t and rename BUS_DMAMEM_NOSYNC to
BUS_DMA_COHERENT.

thorpej 03a0c2d900 Implement a simple queueing mechanism that makes these drivers much
more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.

Thanks to Brad Spencer for the testing help.

thorpej b01dbb214c When creating mscps, be a little more informative about why we couldn't
should creation/initialization of a mscp fail.  Also, don't panic in
these situations.  Instead, simply return an error condition and allow
the caller to deal with it.  It may be the case that we were able to
create one mscp what we can grab, and continue to hobble along.

Also, fix the mscp freelist fencepost error, similar to aha.c and bha.c

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
