cpumask: arch_send_call_function_ipi_mask: alpha
We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(). We also take the chance to wean the send_ipi_message off the obsolescent for_each_cpu_mask(): making it take a pointer seemed the most natural way to do this.
