- sort the ih_evt_handler list by IPL, higher first. Otherwise some handlers would have been delayed, event if they could run at the current IPL. - As ih_evt_handler is sorted, remove IPLs that have been processed for an event when calling hypervisor_set_ipending() - In hypervisor_set_ipending(), enter the event in ipl_evt_mask only for the lowest IPL. As deffered IPLs are processed high to low, this ensure that hypervisor_enable_event() will be called only when all callbacks have been called for an event. We don't need the evtch_maskcount[] counters any more. Thanks to YAMAMOTO Takashi for ideas and feedback.
