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]
