Looks fine to me.  I'll add it to my large queue of changesets for
Paul to review/pull to marcelo's tree.

FWIW, I talked to a bunch of SCSI folks at OLS about DMA off the stack
and they believe it's all gone in 2.6.  I double-checked and that does
seem to be the case.  Nevertheless, I think we will always be fighting
poorly written drivers so this seems to be a great debug option.
