One difference from the init context is that this function can be called before there is a gem object (and thus the guc->ads_map) to calculare the size of the golden context that should be allocated for that object. So in this case the function needs to be prepared for not having the system_info with enabled engines filled out. To accomplish that an info_map is prepared on the side to point either to the gem object or the local variable on the stack. This allows making fill_engine_enable_masks() operate always with a iosys_map argument.
