3.18.27-rt27-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Sebastian Andrzej Siewior We unlock the lock while the interrupts are off. This isn't a problem now but will get because the migrate_disable() + enable are not symmetrical in regard to the status of interrupts.
