Merge tag 'kvm-arm-for-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-next
KVM/ARM changes for Linux v4.5 - Complete rewrite of the arm64 world switch in C, hopefully paving the way for more sharing with the 32bit code, better maintainability and easier integration of new features. Also smaller and slightly faster in some cases... - Support for 16bit VM identifiers - Various cleanups
