From ae5515d66362b9d96cdcfce504567f0b8b7bd83e Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Fri, 4 Dec 2015 08:38:42 -0700 Subject: Revert: "vfio: Include No-IOMMU mode" Revert commit 033291eccbdb ("vfio: Include No-IOMMU mode") due to lack of a user. This was originally intended to fill a need for the DPDK driver, but uptake has been slow so rather than support an unproven kernel interface revert it and revisit when userspace catches up.
