Things like this: -static inline void arch_send_call_function_ipi(cpumask_t mask) +static inline void arch_send_call_function_ipi(cpumask_t *mask) { - smp_ops.send_call_func_ipi(mask); + smp_ops.send_call_func_ipi(*mask); } will still do that stack allocation at the time of the call. You'd have to pass the thing all the way down as a pointer.. Linus
