Subject: [git pull] IOMMU Fixes for Linux v5.5-rc2

Hi Linus,

thanks for taking care of the KASAN related IOMMU fix while I was dived
into other development work and sorry for the inconvenience. Here are
the other IOMMU fixes that piled up during the last weeks:

The following changes since commit d1eef1c619749b2a57e514a3fa67d9a516ffa919:

  iommu/dma: Relax locking in iommu_dma_prepare_msi() (2019-12-18 17:41:36 +0100)

----------------------------------------------------------------
IOMMU Fixes for Linux v5.5-rc2

Including:

	- Fix kmemleak warning in IOVA code

	- Fix compile warnings on ARM32/64 in dma-iommu code due to
	  dma_mask type mismatches

	- Make ISA reserved regions relaxable, so that VFIO can assign
	  devices which have such regions defined

	- Fix mapping errors resulting in IO page-faults in the VT-d
	  driver

	- Make sure direct mappings for a domain are created after the
	  default domain is updated

	- Map ISA reserved regions in the VT-d driver with correct
	  permissions

	- Remove unneeded check for PSI capability in the IOTLB flush
	  code of the VT-d driver

	- Lockdep fix iommu_dma_prepare_msi()

----------------------------------------------------------------
Alex Williamson (1):
      iommu/vt-d: Set ISA bridge reserved region as relaxable

Jerry Snitselaar (2):
      iommu: set group default domain before creating direct mappings
      iommu/vt-d: Allocate reserved region for ISA with correct permission

Lu Baolu (2):
      iommu/vt-d: Fix dmar pte read access not set error
      iommu/vt-d: Remove incorrect PSI capability check

Robin Murphy (2):
      iommu/dma: Rationalise types for DMA masks
      iommu/dma: Relax locking in iommu_dma_prepare_msi()

Xiaotao Yin (1):
      iommu/iova: Init the struct iova to fix the possible memleak
