Will be necessary for ARM later I applied up to here (wrt #4 and flush_tlb_domain(d) I figured that would be a follow up patch). > - #6-#8: Small changes in amd and vtd IOMMU drivers #6 was acked but since the other amd change in #7 wasn't I thought I would wait and take these all in one go. > - #10-#11: Add new device tree helpers I applied these. The rest I think had comments and I couldn't see anything else which could go in independently. Ian.
