[RFC PATCH 0/2] iommu/s390: Fix iommu-groups and add sysfs support

Hey, here are two patches for the s390 PCI and IOMMU code. It is based on the assumption that every pci_dev that points to the same zpci_dev shares a single dma-table (and thus a single address space). If this assupmtion is true (as it looks to me from reading the code) then the iommu-group setup

[PATCH 1/2] iommu/s390: Fix IOMMU groups

From: Joerg Roedel Currently the s390 iommu driver allocates an iommu-group for every device that is added. But that is wrong, as there is only one dma-table per pci-root-bus. Make all devices behind one dma-table share one iommu-group. Signed-off-by: Joerg Roedel --- arch/s390/include/asm/pci
