KVM will refuse to initialise otherwise - Correctly handle 52bit VAs for guest EL2 stage-1 translations when running under NV with E2H==0 - Correctly deal with permission faults in guest_memfd memslots - Fix the steal-time selftest after the infrastructure was reworked - Make sure the host cannot pass a non-sensical clock update to the EL2 tracing infrastructure - Appoint Steffen Eiden as a reviewer in anticipation of the KVM/s390 ability to run arm64 guests, which will inevitably lead to arm64 code being directly used on s390 - Make sure that EL2 is configured with both exception entry and exit being Context Synchronization Events - Handle the current vcpu being NULL on EL2 panic - Fix the selftest_vcpu memcache being empty at the point of donation or sharing - Check that the memcache has enough capacity before engaging on the share/donate path - Fix __deactivate_fgt() to use its parameter rather than a variable in the macro context s390: - Fix array overrun with large amounts of PCI devices x86: - Never use L0's PAUSE loop exiting while L2 is running, since it's unlikely that a nested guest will help solving the hypervisor's spinlock contention - Fix emulation of MOVNTDQA - Fix typo in Xen hypercall tracepoint - Add back an optimization that was left behind when recently fixing a bug - Add module parameter to disable CET, whose implementation seems to have issues. For now it remains enabled by default Generic: - Reject offset causing an unsigned overflow in kvm_reset_dirty_gfn() Documentation: - Update stale links Selftests: - Fix guest_memfd_test with host page size > guest page size"* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (22 commits) KVM: VMX: introduce module parameter to disable CET KVM: x86: Swap the dst and src operand for MOVNTDQA KVM: x86: use again the flush argument of __link_shadow_page() KVM: selftests: Ensure gmem file sizes are multiple of host page size Documentation: kvm: update links in the references section of AMD Memory Encryption KVM: nSVM: Never use L0's PAUSE loop exiting while L2 is running KVM: x86: Fix Xen hypercall tracepoint argument assignment KVM: Reject wrapped offset in kvm_reset_dirty_gfn() KVM: arm64: Pre-check vcpu memcache for host->guest donate KVM: arm64: Pre-check vcpu memcache for host->guest share KVM: arm64: Seed pkvm_ownership_selftest vcpu memcache KVM: arm64: Fix __deactivate_fgt macro parameter typo KVM: arm64: Guard against NULL vcpu on VHE hyp panic path KVM: arm64: Make EL2 exception entry and exit context-synchronization events MAINTAINERS: Add Steffen as reviewer for KVM/arm64 KVM: arm64: Remove potential UB on nvhe tracing clock update KVM: selftests: arm64: Fix steal_time test after UAPI refactoring KVM: arm64: Handle permission faults with guest_memfd KVM: arm64: nv: Consider the DS bit when translating TCR_EL2 KVM: arm64: Work around C1-Pro erratum 4193714 for protected guests ...
