/*
* These flags determine whether or not an event can be associated with an
* interrupt. Static events are permanently associated with an interrupt, and
* can't be changed at runtime. Association of dynamic events with interrupts
* can be changed at run time using the SDEI_INTERRUPT_BIND and
* SDEI_INTERRUPT_RELEASE calls.
*
* SDEI_MAPF_DYNAMIC only indicates run time configurability, where as
* SDEI_MAPF_BOUND indicates interrupt association. For example:
*
* - Calling SDEI_INTERRUPT_BIND on a dynamic event will have both
* SDEI_MAPF_DYNAMIC and SDEI_MAPF_BOUND set.
*
* - Statically-bound events will always have SDEI_MAPF_BOUND set, and neither
* SDEI_INTERRUPT_BIND nor SDEI_INTERRUPT_RELEASE can be called on them.
*
* See also the is_map_bound() macro.
