There are some inconsistencies in how I handle errors which prevents
us from validating these properly:
KVM: PPC: Check if IOMMU page is contained in the pinned physical page
KVM: PPC: Book3S: Fix guest DMA when guest partially backed by THP pages


This is based on sha1
ff69279 Ard Biesheuvel "powerpc: disable support for relative ksymtab references".

Please comment. Thanks.



Alexey Kardashevskiy (4):
  KVM: PPC: Validate all tces before updating tables
  KVM: PPC: Inform the userspace about TCE update failures
  KVM: PPC: Validate TCEs against preregistered memory page sizes
  KVM: PPC: Propagate errors to the guest when failed instead of
    ignoring
