![]() The only user of MSG_ALL_BUT_SELF in the whole kernel tree is powerpc, and it only uses it to start the debugger. Both debuggers always call smp_send_debugger_break with MSG_ALL_BUT_SELF, and only mpic can do anything more optimal than a loop over all online cpus, but all message passing implementations have to code for this special delivery target. Convert smp_send_debugger_break to take void and loop calling the smp_ops message_pass function for each of the other cpus in the online cpumask. Use raw_smp_processor_id() because we are either entering the debugger or trying to start kdump and the additional warning it not useful were it to trigger.
