Update of /a/cvsroot/src/sys/scsi
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv7844

Modified Files:
	cd.c scsi_base.c scsiconf.h sd.c 
Log Message:
Handle cases like the following:
	- controller calls scsi_done() with error XS_TIMEOUT
	- scsi_done() calls sddone()
	- sddone() calls disk_unbusy()
	- scsi_done() calls controller to retry command (missing the
	  call to disk_busy())
	- controller calls scsi_done()
	- scsi_done() calls sddone()
	- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

Update of /a/cvsroot/src/sys/arch/sparc/dev
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv7792

Modified Files:
	xd.c 
Log Message:
we no longer need to add in the offset to the mapped VA to get the correct
device address (bus_tmp, bus_map, and mapiodev now do this for us).

also, we handle all our mappings, so don't have obio.c do any for us
(i.e. don't set ra->ra_len in xdcmatch).
