We use PHYSDEVOP_pirq_eoi_gmfn_v2 to map the bitmap, then if we succeed we use pirq_eoi_map to check whether pirqs need eoi. Changes in v3: - explicitly use PHYSDEVOP_pirq_eoi_gmfn_v2 rather than PHYSDEVOP_pirq_eoi_gmfn; - introduce pirq_check_eoi_map, a function to check if a pirq needs an eoi using the map; -rename pirq_needs_eoi into pirq_needs_eoi_flag; - introduce a function pointer called pirq_needs_eoi that is going to be set to the right implementation depending on the availability of PHYSDEVOP_pirq_eoi_gmfn_v2.
