Linus, The following changes since commit 9ccce092fc64d19504fa54de4fd659e279cc92e7: Merge tag 'for-linus-5.13-ofs-1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux (2021-05-02 14:13:46 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to ce7ea0cfdc2e9ff31d12da31c3226deddb9644f5: KVM: SVM: Move GHCB unmapping to fix RCU warning (2021-05-07 06:06:23 -0400) Thomas Gleixner and Michael Ellerman had some KVM changes in their late merge window pull requests, but there are no conflicts. ---------------------------------------------------------------- * Lots of bug fixes. * Fix virtualization of RDPID * Virtualization of DR6_BUS_LOCK, which on bare metal is new in the 5.13 merge window * More nested virtualization migration fixes (nSVM and eVMCS) * Fix for KVM guest hibernation * Fix for warning in SEV-ES SRCU usage * Block KVM from loading on AMD machines with 5-level page tables, due to the APM not mentioning how host CR4.LA57 exactly impacts the guest. ---------------------------------------------------------------- Benjamin Segall (1): kvm: exit halt polling on need_resched() as well Bill Wendling (1): selftests: kvm: remove reassignment of non-absolute variables Chenyi Qiang (1): KVM: X86: Add support for the emulation of DR6_BUS_LOCK bit Colin Ian King (1): KVM: x86: Fix potential fput on a null source_kvm_file David Matlack (1): kvm: Cap halt polling at kvm->max_halt_poll_ns Kai Huang (2): KVM: x86/mmu: Avoid unnecessary page table allocation in kvm_tdp_mmu_map() KVM: x86/mmu: Fix kdoc of __handle_changed_spte Maxim Levitsky (5): KVM: nSVM: fix a typo in svm_leave_nested KVM: nSVM: fix few bugs in the vmcb02 caching logic KVM: nSVM: leave the guest mode prior to loading a nested state KVM: nSVM: always restore the L1's GIF on migration KVM: nSVM: remove a warning about vmcb01 VM exit reason Nicholas Piggin (1): KVM: PPC: Book3S HV: Fix conversion to gfn-based MMU notifier callbacks Paolo Bonzini (1): KVM: X86: Expose bus lock debug exception to guest Sean Christopherson (17): KVM: VMX: Do not advertise RDPID if ENABLE_RDTSCP control is unsupported KVM: x86: Emulate RDPID only if RDTSCP is supported KVM: SVM: Inject #UD on RDTSCP when it should be disabled in the guest KVM: x86: Move RDPID emulation intercept to its own enum KVM: VMX: Disable preemption when probing user return MSRs KVM: SVM: Probe and load MSR_TSC_AUX regardless of RDTSCP support in host KVM: x86: Add support for RDPID without RDTSCP KVM: VMX: Configure list of user return MSRs at module init KVM: VMX: Use flag to indicate "active" uret MSRs instead of sorting list KVM: VMX: Use common x86's uret MSR list as the one true list KVM: VMX: Disable loading of TSX_CTRL MSR the more conventional way KVM: x86: Export the number of uret MSRs to vendor modules KVM: x86: Move uret MSR slot management to common x86 KVM: x86: Tie Intel and AMD behavior for MSR_TSC_AUX to guest CPU model KVM: x86: Hide RDTSCP and RDPID if MSR_TSC_AUX probing failed KVM: x86: Prevent KVM SVM from loading on kernels with 5-level paging KVM: SVM: Invert user pointer casting in SEV {en,de}crypt helpers Shahin, Md Shahadat Hossain (1): kvm/x86: Fix 'lpages' kvm stat for TDM MMU Siddharth Chandrasekaran (2): doc/kvm: Fix wrong entry for KVM_CAP_X86_MSR_FILTER KVM: x86: Hoist input checks in kvm_add_msr_filter() Stefan Raspl (1): tools/kvm_stat: Fix documentation typo Thomas Gleixner (2): KVM: x86: Cancel pvclock_gtod_work on module removal KVM: x86: Prevent deadlock against tk_core.seq Tom Lendacky (1): KVM: SVM: Move GHCB unmapping to fix RCU warning Vitaly Kuznetsov (9): x86/kvm: Fix pr_info() for async PF setup/teardown x86/kvm: Teardown PV features on boot CPU as well x86/kvm: Disable kvmclock on all CPUs on shutdown x86/kvm: Disable all PV features on crash x86/kvm: Unify kvm_pv_guest_cpu_reboot() with kvm_guest_cpu_offline() KVM: nVMX: Always make an attempt to map eVMCS after migration KVM: selftests: evmcs_test: Check that VMLAUNCH with bogus EVMPTR is causing #UD KVM: selftests: evmcs_test: Check that VMCS12 is alway properly synced to eVMCS after restore KVM: nVMX: Properly pad 'struct kvm_vmx_nested_state_hdr' Wanpeng Li (1): KVM: LAPIC: Accurately guarantee busy wait for timer to expire when using hv_timer
