Subject: [PATCH 00/11] NCR5380: Bug fixes and other improvements

This series begins with some work on the mac_scsi driver to improve
compatibility with SCSI2SD v5 devices. Better error handling is needed
there because the PDMA hardware does not tolerate the write latency spikes
which SD cards can produce.

A bug is fixed in the 5380 core driver so that scatter/gather can be
enabled in mac_scsi.

Several patches at the end of this series improve robustness and correctness
in the core driver.

This series has been tested on a variety of mac_scsi hosts. A variety of
SCSI targets was also tested, including Quantum HDD, Fujitsu HDD, Iomega FDD,
Ricoh CD-RW, Matsushita CD-ROM, SCSI2SD and BlueSCSI.
