cpumask: arch_send_call_function_ipi_mask: mips
We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(), and by defining it, the old arch_send_call_function_ipi is defined by the core code. We also take the chance to wean the implementations off the obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer seemed the most natural way to ensure all implementations used for_each_cpu.
