[PATCH kernel 0/3] Enable IOMMU support for pseries Secure VMs

This enables IOMMU for SVM. Instead of sharing
a H_PUT_TCE_INDIRECT page, this uses H_PUT_TCE for mapping
and H_STUFF_TCE for clearing TCEs which should bring
acceptable performance at the boot time; otherwise things
work with the same speed anyway.

Please comment. Thanks.



Alexey Kardashevskiy (2):
  powerpc/pseries: Allow not having
    ibm,hypertas-functions::hcall-multi-tce for DDW
  powerpc/pseries/iommu: Do not use H_PUT_TCE_INDIRECT in secure VM

Ram Pai (1):
  powerpc/pseries/iommu: Use dma_iommu_ops for Secure VM.
