This patch series enables IOMMU support for pseries Secure VMs.


Tested using QEMU command line option:

 "-device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x4,
 	iommu_platform=on,disable-modern=off,disable-legacy=on"
 and 

 "-device virtio-blk-pci,scsi=off,bus=pci.0,
 	addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,
 	iommu_platform=on,disable-modern=off,disable-legacy=on"

Ram Pai (2):
  powerpc/pseries/iommu: Share the per-cpu TCE page with the hypervisor.
  powerpc/pseries/iommu: Use dma_iommu_ops for Secure VMs aswell.
