From 7d43c2e42cb1e436f97c1763150e4e1122ae0d57 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 30 May 2012 14:19:55 -0600 Subject: iommu: Remove group_mf The iommu=group_mf is really no longer needed with the addition of ACS support in IOMMU drivers creating groups. Most multifunction devices will now be grouped already. If a device has gone to the trouble of exposing ACS, trust that it works. We can use the device specific ACS function for fixing devices we trust individually. This largely reverts bcb71abe.
