We should not use physid_mask_t as a stack based variable in apic code. This type depends on MAX_APICS parameter which may be huge enough. Especially it became a problem with apic NOOP driver which is portable between 32 bit and 64 bit environment (where we have really huge MAX_APICS). So apic driver should operate with pointers and a caller in turn should aware of allocation physid_mask_t variable. As a side (but positive) effect -- we may use already implemented physid_set_mask_of_physid function eliminating default_apicid_to_cpu_present completely. Note that physids_coerce and physids_promote turned into static inline from macro (since macro hides the fact that parameter is being interpreted as unsigned long, make it explicit).
