These are the PCI related patches from the previously submitted v2 IOMMU Groups + VFIO series. I've updated them with Don's comments and split them off on their own so that we can hopefully make some progress getting these in. Patches are against 20120529 linux-next tree. Patches 1 & 2 provide DMA quirking and ACS checking which will be used by IOMMU drivers supporting IOMMU groups. Patch 3 enables the set of pci user config access functions to be called from other modules, which will be used by VFIO-pci. Patch 4 enables a common translation of pcibios errors into errno for returning to userspace, also to be used by VFIO-pci. Patch 5 adds additional PCI register definitions so we can more easily parse config space for devices in VFIO-pci. These patches, as well as IOMMU group support and VFIO can be found in git here: git://github.com/awilliam/linux-vfio.git (iommu-group-vfio-next-20120529) Please consider these for 3.5, but I'll settle for any kind of next branch.
