[PATCH 0/4] powerpc iommu: extending real mode support

[aik]

From: Alexey Kardashevskiy <aik@xxxxxxxxx>

The first 2 patches in this set add a multi-tce support feature
(adding/deleting several TCE records at once) in real and virtual mode.

The last 2 patches enable real mode acceleration for VFIO and
extend the multi-tce feature to be available for VFIO devices.

The QEMU change is required in order to support this functionality
(additional ioctl to add a new LIOBN and hook it with a specific IOMMU)).


Alexey Kardashevskiy (4):
  powerpc: lookup_linux_pte has been made public
  powerpc kvm: added multiple TCEs requests support
  powerpc: preparing to support real mode optimization
  vfio powerpc: added real mode support
