Merge tag 'kvm-4.14-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Radim Krčmář: "First batch of KVM changes for 4.14 Common: - improve heuristic for boosting preempted spinlocks by ignoring VCPUs in user mode ARM: - fix for decoding external abort types from guests - added support for migrating the active priority of interrupts when running a GICv2 guest on a GICv3 host - minor cleanup PPC: - expose storage keys to userspace - merge kvm-ppc-fixes with a fix that missed 4.13 because of vacations - fixes s390: - merge of kvm/master to avoid conflicts with additional sthyi fixes - wire up the no-dat enhancements in KVM - multiple epoch facility (z14 feature) - Configuration z/Architecture Mode - more sthyi fixes - gdb server range checking fix - small code cleanups x86: - emulate Hyper-V TSC frequency MSRs - add nested INVPCID - emulate EPTP switching VMFUNC - support Virtual GIF - support 5 level page tables - speedup nested VM exits by packing byte operations - speedup MMIO by using hardware provided physical address - a lot of fixes and cleanups, especially nested" * tag 'kvm-4.14-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (67 commits) KVM: arm/arm64: Support uaccess of GICC_APRn KVM: arm/arm64: Extract GICv3 max APRn index calculation KVM: arm/arm64: vITS: Drop its_ite->lpi field KVM: arm/arm64: vgic: constify seq_operations and file_operations KVM: arm/arm64: Fix guest external abort matching KVM: PPC: Book3S HV: Fix memory leak in kvm_vm_ioctl_get_htab_fd KVM: s390: vsie: cleanup mcck reinjection KVM: s390: use WARN_ON_ONCE only for checking KVM: s390: guestdbg: fix range check KVM: PPC: Book3S HV: Report storage key support to userspace KVM: PPC: Book3S HV: Fix case where HDEC is treated as 32-bit on POWER9 KVM: PPC: Book3S HV: Fix invalid use of register expression KVM: PPC: Book3S HV: Fix H_REGISTER_VPA VPA size validation KVM: PPC: Book3S HV: Fix setting of storage key in H_ENTER KVM: PPC: e500mc: Fix a NULL dereference KVM: PPC: e500: Fix some NULL dereferences on error KVM: PPC: Book3S HV: Protect updates to spapr_tce_tables list KVM: s390: we are always in czam mode KVM: s390: expose no-DAT to guest and migration support KVM: s390: sthyi: remove invalid guest write access ...
