Paul Burton 91951f980e irqchip/mips-gic: Don't overrun pcpu_masks array ... Commit 2a07870511 ("irqchip/mips-gic: Use gic_vpes instead of NR_CPUS") & commit 78930f09b9 ("irqchip/mips-gic: Clear percpu_masks correctly when mapping") both introduce code which accesses gic_vpes entries in the pcpu_masks array. However, this array has length NR_CPUS. If NR_CPUS is less than gic_vpes (ie. the kernel supports use of less CPUs than are present in the system) then we overrun the array, clobber some other data & generally die pretty promptly. Most notably this affects uniprocessor kernels running on any multicore or multithreaded Malta with a GIC (ie. the vast majority of real Malta boards). Fix this by only accessing up to min(gic_vpes, NR_CPUS) entries in the pcpu_masks array, preventing the array overrun.
