iommu/amd: Reserve exclusion range in iova-domain (2019-03-29 17:12:57 +0100)

----------------------------------------------------------------
IOMMU Fixes for Linux v5.1-rc3

Including:

- Fix a bug in the AMD IOMMU driver not handling exclusion ranges
correctly. In fact the driver did not reserve these ranges for
IOVA allocations, so that dma-handles could be allocated in an
exclusion range, leading to data corruption. Exclusion ranges
have not been used by any firmware up to now, so this issue
remained undiscovered for quite some time.

- Fix wrong warning messages that the IOMMU core code prints
when it tries to allocate the default domain for an iommu
group and the driver does not support any of the default
domain types (like Intel VT-d).

----------------------------------------------------------------
