[RFC PATCH 00/34] iommu: Move iommu_group setup to IOMMU core code
Hi,
here is a patch-set to remove all calls of iommu_group_get_for_dev() from

allocation into the IOMMU core code.
This eliminates some ugly back and forth between IOMMU core code and the
IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself
called back into the driver.
