Okay, I updated this branch (non-fast-forward) with my current state. It
includes the fixes for Joe's objection and for all problems reported by
Fengguang Wu. While at it I added a patch to fix most of the other
sparse warnings in the AMD IOMMU driver. Thanks again for the reports
guys :)
I will wait for more comments and fixes to come up (including the
rewrite of patch 3 as requested by Ingo) and repost the patch-set some
time next week.
Thanks so far,
Joerg
