Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Paolo Bonzini: "Selftest changes: - Cleanups for the perf test infrastructure and mapping hugepages - Avoid contention on mmap_sem when the guests start to run - Add event channel upcall support to xen_shinfo_test x86 changes: - Fixes for Xen emulation - Kill kvm_map_gfn() / kvm_unmap_gfn() and broken gfn_to_pfn_cache - Fixes for migration of 32-bit nested guests on 64-bit hypervisor - Compilation fixes - More SEV cleanups Generic: - Cap the return value of KVM_CAP_NR_VCPUS to both KVM_CAP_MAX_VCPUS and num_online_cpus(). Most architectures were only using one of the two" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (42 commits) KVM: x86: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: s390: Cap KVM_CAP_NR_VCPUS by num_online_cpus() KVM: RISC-V: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: PPC: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: MIPS: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: arm64: Cap KVM_CAP_NR_VCPUS by kvm_arm_default_max_vcpus() KVM: x86: Assume a 64-bit hypercall for guests with protected state selftests: KVM: Add /x86_64/sev_migrate_tests to .gitignore riscv: kvm: fix non-kernel-doc comment block KVM: SEV: Fix typo in and tweak name of cmd_allowed_from_miror() KVM: SEV: Drop a redundant setting of sev->asid during initialization KVM: SEV: WARN if SEV-ES is marked active but SEV is not KVM: SEV: Set sev_info.active after initial checks in sev_guest_init() KVM: SEV: Disallow COPY_ENC_CONTEXT_FROM if target has created vCPUs KVM: Kill kvm_map_gfn() / kvm_unmap_gfn() and gfn_to_pfn_cache KVM: nVMX: Use a gfn_to_hva_cache for vmptrld KVM: nVMX: Use kvm_read_guest_offset_cached() for nested VMCS check KVM: x86/xen: Use sizeof_field() instead of open-coding it KVM: nVMX: Use kvm_{read,write}_guest_cached() for shadow_vmcs12 KVM: x86/xen: Fix get_attr of KVM_XEN_ATTR_TYPE_SHARED_INFO ...
