From d5776325eac88409c5b58a9d45fb33fd2b183f70 Mon Sep 17 00:00:00 2001 From: Mitchel Humpherys Date: Fri, 12 Feb 2016 13:53:20 -0800 Subject: iommu: Add DOMAIN_ATTR_FAST for requesting a fast domain Some IOMMU drivers offer "fast" page table management routines for special cases. There is often a trade-off with memory, etc. with these so make their usage explicit with a domain attribute.
