- 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
- Reverted a couple of fixes for RCU stalls when destroying a stage-2
page table. There appears to be some nasty refcounting / UAF issues
lurking in those patches and the band-aid we tried to apply didn't
hold.
s390:
- mm fixes, including userfaultfd bug fix
x86:
- Sync the vTPR from the local APIC to the VMCB even when AVIC is active.
This fixes a bug where host updates to the vTPR, e.g. via KVM_SET_LAPIC or
emulation of a guest access, are lost and result in interrupt delivery
issues in the guest.

"These are mostly Oliver's Arm changes: lock ordering fixes for the
