The commitlime2-spi21b3edfc96
("efi_loader: check parameters of CreateEvent") enforces a strict parameter check at CreateEvent(). On the other hand, UEFI specification version 2.7, section 7.1, says: The EVT_NOTIFY_WAIT and EVT_NOTIFY_SIGNAL flags are exclusive. If neither flag is specified, the caller does not require any notification concerning the event and the NotifyTpl, NotifyFunction, and NotifyContext parameters are ignored. So the check should be mitigated so as to comply with the specification. Without this patch, EDK2's Shell.efi won't be started. Fixes:21b3edfc96
