This mostly contains a bunch of cleanups now that can be done now that we are free of the 32bit legacy, and a number of refactoring patches that prepare for the eventual landing of the dreaded nested virt patches. Two things though: - there is another bunch of patches that I have routed via the arm64 tree as they would otherwise very badly conflict if taken via the KVM tree - Depending on how things go during the first week, I may have another small set of patches that I'm holding back for now as they also conflict very badly with Mike Rapoport's P4D patches. Please pull, M.
