[PATCH v4 0/6] Optimise 64-bit IOVA allocations

From: Robin Murphy
Date: Tue Sep 19 2017 - 12:32:10 EST


v3: https://www.mail-archive.com/iommu@xxxxxxxxxxxxxxxxxxxxxxxxxx/msg19694.html

This was supposed to be just a rebase and repost, but in the meantime I
kept scratching the itch and ended up with two extra patches to simplify
the end result even more - the series was least churny with them added
in the middle, but #5 and #6 remain essentially unchanged from v3, such
that I'm happy the tested-bys all remain valid.

Robin.
