[PATCH v1 00/13] powerpc: kvm: Enable in-kernel acceleration for VFIO

[Alexey Kardashevskiy]

This enables in-kernel acceleration of TCE hypercalls (H_PUT_TCE,
H_PUT_TCE_INDIRECT, H_STUFF_TCE). This implements acceleration
for both real and virtual modes.

This was made on top of both:
[PATCH v1 00/16] powernv: vfio: Add Dynamic DMA windows (DDW)
[PATCH v1 0/7] powerpc/iommu: kvm: Enable MultiTCE support


Alexey Kardashevskiy (13):
  KVM: PPC: Account TCE pages in locked_vm
  KVM: PPC: Rework kvmppc_spapr_tce_table to support variable page size
  KVM: PPC: Enable IOMMU_API for KVM_BOOK3S_64 permanently
  KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_VFIO capability number
  KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_64 capability number
  KVM: PPC: Add @offset to kvmppc_spapr_tce_table
