Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull more KVM updates from Paolo Bonzini: "PPC: - Improvements and bugfixes for secure VM support, giving reduced startup time and memory hotplug support. - Locking fixes in nested KVM code - Increase number of guests supported by HV KVM to 4094 - Preliminary POWER10 support ARM: - Split the VHE and nVHE hypervisor code bases, build the EL2 code separately, allowing for the VHE code to now be built with instrumentation - Level-based TLB invalidation support - Restructure of the vcpu register storage to accomodate the NV code - Pointer Authentication available for guests on nVHE hosts - Simplification of the system register table parsing - MMU cleanups and fixes - A number of post-32bit cleanups and other fixes MIPS: - compilation fixes x86: - bugfixes - support for the SERIALIZE instruction" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (70 commits) KVM: MIPS/VZ: Fix build error caused by 'kvm_run' cleanup x86/kvm/hyper-v: Synic default SCONTROL MSR needs to be enabled MIPS: KVM: Convert a fallthrough comment to fallthrough MIPS: VZ: Only include loongson_regs.h for CPU_LOONGSON64 x86: Expose SERIALIZE for supported cpuid KVM: x86: Don't attempt to load PDPTRs when 64-bit mode is enabled KVM: arm64: Move S1PTW S2 fault logic out of io_mem_abort() KVM: arm64: Don't skip cache maintenance for read-only memslots KVM: arm64: Handle data and instruction external aborts the same way KVM: arm64: Rename kvm_vcpu_dabt_isextabt() KVM: arm: Add trace name for ARM_NISV KVM: arm64: Ensure that all nVHE hyp code is in .hyp.text KVM: arm64: Substitute RANDOMIZE_BASE for HARDEN_EL2_VECTORS KVM: arm64: Make nVHE ASLR conditional on RANDOMIZE_BASE KVM: PPC: Book3S HV: Rework secure mem slot dropping KVM: PPC: Book3S HV: Move kvmppc_svm_page_out up KVM: PPC: Book3S HV: Migrate hot plugged memory KVM: PPC: Book3S HV: In H_SVM_INIT_DONE, migrate remaining normal-GFNs to secure-GFNs KVM: PPC: Book3S HV: Track the state GFNs associated with secure VMs KVM: PPC: Book3S HV: Disable page merging in H_SVM_INIT_START ...
