Problem Details: Since pr_debug() has changed from a macro to an inline function when DEBUG is not defined, its arguments now need to be defined even when debugging is off. Therefore to_event_str() and to_qp_state_str() need to be moved out of #ifdef DEBUG. The compiler will throw the definitions away if DEBUG is not...

Problem Details: If the ib_cm module is unloaded while id's are still in timewait, the CM will destroy the work queue used to process timewait. Once the id's exit timewait, their timers will fire, leading to a crash trying to access the destroyed work queue. We need to track id's that are in timewait, and cancel thei...

Problem Details: On the old "powersurge" SMP powermacs, the second CPU is started up by sending it an IPI, which has the side effect of stopping the timebase clock (so the secondary CPU's timebase can be synchronized with the primary's).
