This is based on Linus'es tree sha1 c1aa905a304e. Please comment. Thanks. Changes: v8: * kept fixing oddities with error handling in 10/10 v7: * added realmode's WARN_ON_ONCE_RM in arch/powerpc/kvm/book3s_64_vio_hv.c v6: * reworked the last patch in terms of error handling and parameters checking v5: * replaced "KVM: PPC: Separate TCE validation from update" with "KVM: PPC: iommu: Unify TCE checking" * changed already reviewed "powerpc/iommu/vfio_spapr_tce: Cleanup iommu_table disposal" * reworked "KVM: PPC: VFIO: Add in-kernel acceleration for VFIO" * more details in individual commit logs v4: * addressed comments from v3 * updated subject lines with correct component names * regrouped the patchset in order: - powerpc fixes; - vfio_spapr_tce driver fixes; - KVM/PPC fixes; - KVM+PPC+VFIO; * everything except last 2 patches have "Reviewed-By: David" v3: * there was no full repost, only last patch was posted v2: * 11/11 reworked to use new notifiers, it is rather RFC as it still has a issue; * got 09/11, 10/11 to use notifiers in 11/11; * added rb: David to most of patches and added a comment in 05/11.
