I'm backporting this to the stable releases, and I'm a bit worried about the above comment. The new Scheduler IPI code uses work queues and requires it to be done in a hard irq.
The IPI part is only done for the high-prio which is only used by NOHZ. Everyone else gets in via softiq as we did it before.
