Pull iommu fixes from Joerg Roedel: - 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() * tag 'iommu-fixes-v5.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/dma: Relax locking in iommu_dma_prepare_msi() iommu/vt-d: Remove incorrect PSI capability check iommu/vt-d: Allocate reserved region for ISA with correct permission iommu: set group default domain before creating direct mappings iommu/vt-d: Fix dmar pte read access not set error iommu/vt-d: Set ISA bridge reserved region as relaxable iommu/dma: Rationalise types for DMA masks iommu/iova: Init the struct iova to fix the possible memleak
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
