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"
changelog: v4: Corrected the Subject, to include the keyword 'PATCH'. No other changes.
v3: Better description of 2/2 patch. Suggested by David Gibson.
v2: added comments describing the changes. Suggested by Alexey and Michael Ellermen.
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.
