In some of the PPC970 based systems, interrupt would be distributed to offline cpus also even when booted with "maxcpus=1". So check whether cpu online map and cpu present map are equal or not. If they are equal default_distrib_server is used as interrupt server otherwise boot cpu (default_server) used as interrupt server. In addition to this, if an interrupt is assigned to a specific cpu (ie smp affinity) and if that cpu is not online, the earlier code used to return the default_distrib_server as interrupt server. This introduces an additional parameter to the get_irq function, called strict_check. Based on this parameter, if the cpu is not online either default_distrib_server or -1 is returned.
