x86, mce: Replace MCE_SELF_VECTOR by irq_work
The MCE handler uses a special vector for self IPI to invoke post-emergency processing in an interrupt context, e.g. call an NMI-unsafe function, wakeup loggers, schedule time-consuming work for recovery, etc. This mechanism is now generalized by the following commit: > e360adbe29241a0194e10e20595360dd7b98a2b3 > Author: Peter Zijlstra <a.p.zijlstra@chello.nl> > Date: Thu Oct 14 14:01:34 2010 +0800 > > irq_work: Add generic hardirq context callbacks > > Provide a mechanism that allows running code in IRQ context. It is > most useful for NMI code that needs to interact with the rest of the > system -- like wakeup a task to drain buffers. : So change to use provided generic mechanism.
