Subject: [PATCH v4 00/07] iommu/ipmmu-vmsa: IPMMU multi-arch update V4

iommu/ipmmu-vmsa: IPMMU multi-arch update V4

[PATCH v4 01/07] iommu/ipmmu-vmsa: Remove platform data handling
[PATCH v4 02/07] iommu/ipmmu-vmsa: Rework interrupt code and use bitmap for context
[PATCH v4 03/07] iommu/ipmmu-vmsa: Break out utlb parsing code
[PATCH v4 04/07] iommu/ipmmu-vmsa: Break out domain allocation code
[PATCH v4 05/07] iommu/ipmmu-vmsa: Add new IOMMU_DOMAIN_DMA ops
[PATCH v4 06/07] iommu/ipmmu-vmsa: ARM and ARM64 archdata access
[PATCH v4 07/07] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency

These patches update the IPMMU driver with a couple of changes
to support build on multiple architectures. In the process of
doing so the interrupt code gets reworked and the foundation
for supporting multiple contexts are added.

Changes since V3:
 - Updated patch 3/7 to fix hang-on-boot issue on 32-bit ARM - thanks Geert!
 - Reworked group parameter handling in patch 3/7 and 5/7.
 - Added patch 6/7 to fix build of the driver on s390/tile/um architectures

Changes since V2:
 - Got rid of patch 3 from the V2 however patch 1, 2 and 4 are kept.
 - V3 patch 3, 4 and 5 come from
   [PATCH 00/04] iommu/ipmmu-vmsa: IPMMU CONFIG_IOMMU_DMA update
 - Patch 5 has been reworked to include patch 3 of the V1 of this series 

Changes since V1:
 - Got rid of patch 2 and 3 from initial series
 - Updated bitmap code locking and also used lighter bitop functions
 - Updated the Kconfig bits to apply on top of ARCH_RENESAS
