Pull kvm updates from Paolo Bonzini: "Quite a large pull request due to a selftest API overhaul and some patches that had come in too late for 5.19. ARM: - Unwinder implementations for both nVHE modes (classic and protected), complete with an overflow stack - Rework of the sysreg access from userspace, with a complete rewrite of the vgic-v3 view to allign with the rest of the infrastructure - Disagregation of the vcpu flags in separate sets to better track their use model. - A fix for the GICv2-on-v3 selftest - A small set of cosmetic fixes RISC-V: - Track ISA extensions used by Guest using bitmap - Added system instruction emulation framework - Added CSR emulation framework - Added gfp_custom flag in struct kvm_mmu_memory_cache - Added G-stage ioremap() and iounmap() functions - Added support for Svpbmt inside Guest s390: - add an interface to provide a hypervisor dump for secure guests - improve selftests to use TAP interface - enable interpretive execution of zPCI instructions (for PCI passthrough) - First part of deferred teardown - CPU Topology - PV attestation - Minor fixes x86: - Permit guests to ignore single-bit ECC errors - Intel IPI virtualization - Allow getting/setting pending triple fault with KVM_GET/SET_VCPU_EVENTS - PEBS virtualization - Simplify PMU emulation by just using PERF_TYPE_RAW events - More accurate event reinjection on SVM (avoid retrying instructions) - Allow getting/setting the state of the speaker port data bit - Refuse starting the kvm-intel module if VM-Entry/VM-Exit controls are inconsistent - "Notify" VM exit (detect microarchitectural hangs) for Intel - Use try_cmpxchg64 instead of cmpxchg64 - Ignore benign host accesses to PMU MSRs when PMU is disabled - Allow disabling KVM's "MONITOR/MWAIT are NOPs!" behavior - Allow NX huge page mitigation to be disabled on a per-vm basis - Port eager page splitting to shadow MMU as well - Enable CMCI capability by default and handle injected UCNA errors - Expose pid of vcpu threads in debugfs - x2AVIC support for AMD - cleanup PIO emulation - Fixes for LLDT/LTR emulation - Don't require refcounted "struct page" to create huge SPTEs - Miscellaneous cleanups: - MCE MSR emulation - Use separate namespaces for guest PTEs and shadow PTEs bitmasks - PIO emulation - Reorganize rmap API, mostly around rmap destruction - Do not workaround very old KVM bugs for L0 that runs with nesting enabled - new selftests API for CPUID Generic: - Fix races in gfn->pfn cache refresh; do not pin pages tracked by the cache - new selftests API using struct kvm_vcpu instead of a (vm, id) tuple" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (606 commits) selftests: kvm: set rax before vmcall selftests: KVM: Add exponent check for boolean stats selftests: KVM: Provide descriptive assertions in kvm_binary_stats_test selftests: KVM: Check stat name before other fields KVM: x86/mmu: remove unused variable RISC-V: KVM: Add support for Svpbmt inside Guest/VM RISC-V: KVM: Use PAGE_KERNEL_IO in kvm_riscv_gstage_ioremap() RISC-V: KVM: Add G-stage ioremap() and iounmap() functions KVM: Add gfp_custom flag in struct kvm_mmu_memory_cache RISC-V: KVM: Add extensible CSR emulation framework RISC-V: KVM: Add extensible system instruction emulation framework RISC-V: KVM: Factor-out instruction emulation into separate sources RISC-V: KVM: move preempt_disable() call in kvm_arch_vcpu_ioctl_run RISC-V: KVM: Make kvm_riscv_guest_timer_init a void function RISC-V: KVM: Fix variable spelling mistake RISC-V: KVM: Improve ISA extension by using a bitmap KVM, x86/mmu: Fix the comment around kvm_tdp_mmu_zap_leafs() KVM: SVM: Dump Virtual Machine Save Area (VMSA) to klog KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT KVM: x86: Do not block APIC write for non ICR registers ...
