Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Paolo Bonzini: "ARM: - More progress on the protected VM front, now with the full fixed feature set as well as the limitation of some hypercalls after initialisation. - Cleanup of the RAZ/WI sysreg handling, which was pointlessly complicated - Fixes for the vgic placement in the IPA space, together with a bunch of selftests - More memcg accounting of the memory allocated on behalf of a guest - Timer and vgic selftests - Workarounds for the Apple M1 broken vgic implementation - KConfig cleanups - New kvmarm.mode=none option, for those who really dislike us RISC-V: - New KVM port. x86: - New API to control TSC offset from userspace - TSC scaling for nested hypervisors on SVM - Switch masterclock protection from raw_spin_lock to seqcount - Clean up function prototypes in the page fault code and avoid repeated memslot lookups - Convey the exit reason to userspace on emulation failure - Configure time between NX page recovery iterations - Expose Predictive Store Forwarding Disable CPUID leaf - Allocate page tracking data structures lazily (if the i915 KVM-GT functionality is not compiled in) - Cleanups, fixes and optimizations for the shadow MMU code s390: - SIGP Fixes - initial preparations for lazy destroy of secure VMs - storage key improvements/fixes - Log the guest CPNC Starting from this release, KVM-PPC patches will come from Michael Ellerman's PPC tree" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (227 commits) RISC-V: KVM: fix boolreturn.cocci warnings RISC-V: KVM: remove unneeded semicolon RISC-V: KVM: Fix GPA passed to __kvm_riscv_hfence_gvma_xyz() functions RISC-V: KVM: Factor-out FP virtualization into separate sources KVM: s390: add debug statement for diag 318 CPNC data KVM: s390: pv: properly handle page flags for protected guests KVM: s390: Fix handle_sske page fault handling KVM: x86: SGX must obey the KVM_INTERNAL_ERROR_EMULATION protocol KVM: x86: On emulation failure, convey the exit reason, etc. to userspace KVM: x86: Get exit_reason as part of kvm_x86_ops.get_exit_info KVM: x86: Clarify the kvm_run.emulation_failure structure layout KVM: s390: Add a routine for setting userspace CPU state KVM: s390: Simplify SIGP Set Arch handling KVM: s390: pv: avoid stalls when making pages secure KVM: s390: pv: avoid stalls for kvm_s390_pv_init_vm KVM: s390: pv: avoid double free of sida page KVM: s390: pv: add macros for UVC CC values s390/mm: optimize reset_guest_reference_bit() s390/mm: optimize set_guest_storage_key() s390/mm: no need for pte_alloc_map_lock() if we know the pmd is present ...
