Jeff,
Per David's comments, I recommend that this patch be dropped from inclusion.

It's a recent addition, and this series (v2/v3) is just part of the
already-accepted series. Jeff already queued it all up in
libata-dev.git:

A NACK is probably the right thing. I was mostly converting a few
other drivers which used some simple, common patterns to use my new
common code, but this driver was missing it altogether. It looks like
there may be bigger issues, though, as you point out.

I didn't; I don't have a cavium-octeon system.

As noted earlier, I don't have much interest in this driver. I agree
that there are some other issues with the driver; I think it leaks
memory if it is ever allowed to unload, for one. Feel free to submit
an alternative patch to prevent this driver from being built as a
module.
