d70d4667e9 [SCSI] ch: fix sparse shadowed variable warnings
Replace the global err array with ch_err.
drivers/scsi/ch.c:271:6: warning: symbol 'err' shadows an earlier one
drivers/scsi/ch.c:116:3: originally declared here

Replace the temporary cmd buffer with ch_err to avoid shadowing the cmd
function parameter.

f6b196a2f3 [SCSI] hptiop: fix header.context usage
header.context is a 64 bit field, but it's deliberately split into
context and context_hi32.  Thus cpu_to_le64 assignments are wrong on
this.  Replace them with the correct settings of both the low and high
words.

SGI machines with WD33C93 allow usage of burst mode DMA, which increases

setting the values for no_sync, fast and dma_mode has been moved to the

9d56291366 [SCSI] qla4xxx: fix scsi command completion, lun reset and target reset code
This patch contains the following:

1. when hba completion status is good, check for iscsi transport
   errors (underflow/overflow) prior to checking the scsi status

2. New firmware requires that one marker iocb be issued for each task
   management command. The patch issues marker iocb immediately
   following a LUN or Target reset.
