anding lazy ASID regenerations). Unfortunately neither case handles SMP hosts correctly: - When the lazy ASID regeneration is performed it should apply to all CPUs (as last_user_gasid does), so reset the ASID on other CPUs to zero to trigger regeneration when the VCPU is next loaded on those CPUs. - When the ASID is found to be stale on the current CPU, we should not cancel lazy ASID regenerations globally, so drop the reset of last_user_gasid altogether here. Both cases would require a guest ASID change and two host CPU migrations (and in the latter case one of the CPUs to start a new ASID cycle) before guest usermode could potentially access stale user pages from a previously running ASID in the same VCPU.
