Among other improvements, this patch series fixes a data corruption bug in the mac_scsi driver and a bug in the EH abort routine in the core 5380 driver. For consistency I have ignored certain checkpatch.pl complaints about the indentation in mac_scsi.c. The remaining complaints seem to be false positives. Some of these patches are not trivial to backport. Those patches have been nominated for recent -stable branches only.
