Merge tag 'kvmarm-fixes-6.17-2' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 changes for 6.17, round #3 - Invalidate nested MMUs upon freeing the PGD to avoid WARNs when visiting from an MMU notifier - Fixes to the TLB match process and TLB invalidation range for managing the VCNR pseudo-TLB - Prevent SPE from erroneously profiling guests due to UNKNOWN reset values in PMSCR_EL1 - Fix save/restore of host MDCR_EL2 to account for eagerly programming at vcpu_load() on VHE systems - Correct lock ordering when dealing with VGIC LPIs, avoiding scenarios where an xarray's spinlock was nested with a *raw* spinlock - Permit stage-2 read permission aborts which are possible in the case of NV depending on the guest hypervisor's stage-2 translation - Call raw_spin_unlock() instead of the internal spinlock API - Fix parameter ordering when assigning VBAR_EL1 [Pull into kvm/master to fix conflicts. - Paolo]
