MIPS: SGI-IP27: Fix crash, when CPUs are disabled via nr_cpus parameter

Browse source

If number of CPUs are limited by the kernel commandline parameter nr_cpus
assignment of interrupts accourding to numa rules might not be possibe.
As a fallback use one of the online CPUs as interrupt destination.
