We didn't get agreement on patch #5 (#4 in v1) in the former cycle though, I made it based on my understanding. We can continue discussing on it. Changelog: v1->v2: - #1. Reworded commit message and comment, plus some typo fixes. - #2. New patch. - #3. Added the missing suggested-by Pierre. Fixed typos. Added sanity check on pa->pa_iova_pfn and updated comments accordingly. - #4. Removed unused idaw_nr. - #5. Replaced leading white spaces with TABs. Traced the function in anycase.
