[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
the IOMMU drivers and move the per-device group setup and default domain
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.
