Sure. Will add them in next post. > - are there patches ready to be merged here? > if yes pls post them without the rfc tag The series (since V1) should have passed compilation test and simple functional test (though only with my tiny C program to torture it). Since I have got lots of review comments, and looks like the whole thing is acceptable in general, I'll repost with a non-rfc version with some tweaks upon this one. Michael, please feel free to pick any of them which you think are applicable and safe (e.g., the iommu cleanups). Thanks, -- peterx
