This patch (commit b6194b94a2ca, "KVM: VMX: Configure...) has a bug that Maxim found during code review. The bug is eliminated by the very next patch (commit e7f5ab87841c), but it will break bisection if bisection involves running a KVM guest. At a glance, even syzkaller will be affected :-( > 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

Thank you!
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

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

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
