60db402780 drivers/base/iommu.c: add missing includes
Fix zillions of -mm x86_64 allmodconfig build errors - the file uses
EXPORT_SYMBOL() and kmalloc but misses the needed includes.

dbb9fd8630 iommu: Add domain_has_cap iommu_ops
This iommu_op can tell if domain have a specific capability, like snooping
control for Intel IOMMU, which can be used by other components of kernel to
adjust the behaviour.

fc2100eb4d add frontend implementation for the IOMMU API
This API can be used by KVM for accessing different types of IOMMUs to
do device passthrough to guests. Beside that this API can also be used
by device drivers to map non-linear host memory into dma-linear
addresses to prevent sgather-gather DMA. UIO may be another user for
this API.
