Do you think I should fix this and rebase on the latest linux-next
now? I wonder if there are more factor and clean up coming and I
should wait after that.

Here is my preferred plan:

 1) wait for my series to support the min alignment in swiotlb to
    land in Linus tree
 2) I'll resend my series with the further swiotlb cleanup and
    refactoring, which includes a slightly rebased version of your
    patch to add the io_tlb_mem structure
 3) resend your series on top of that as a baseline

This is my current WIP tree for 2:
