Juergen Gross 064b57a8da xen/events: reset active flag for lateeoi events later ... commit 3de218ff39b9e3f0d453fe3154f12a174de44b25 upstream. In order to avoid a race condition for user events when changing cpu affinity reset the active flag only when EOI-ing the event. This is working fine as all user events are lateeoi events. Note that lateeoi_ack_mask_dynirq() is not modified as there is no explicit call to xen_irq_lateeoi() expected later.
