Subject: [PATCH 0/2] iommu/iova: Solve longterm IOVA issue

This series contains a patch to solve the longterm IOVA issue which
leizhen originally tried to address at [0].

I also included the small optimisation from Cong Wang, which never seems
to be have been accepted [1]. There was some debate of the other patches
in that series, but this one is quite straightforward.

@Cong Wang, Please resend your series if prefer I didn't upstream your
patch.
