Hi,

This patchset continues my work to to add P2PDMA support to the common
dma map operations. This allows for creating SGLs that have both P2PDMA
and regular pages which is a necessary step to allowing P2PDMA pages in
userspace.

The earlier RFC[1] generated a lot of great feedback and I heard no show
stopping objections. Thus, I've incorporated all the feedback and have
decided to post this as a proper patch series with hopes of eventually
getting it in mainline.

I'm happy to do a few more passes if anyone has any further feedback
or better ideas.


After an initial pass through these, I think I like the approach. And I
don't have any huge structural comments or new ideas, just smaller comments
and notes.

I'll respond to each patch, but just wanted to say up front that this is
looking promising, in my opinion.


thanks,
