Enabling CONFIG_LOCKUP_DETECTOR help validator tracks the 'state' of lock-classes, and it tracks dependencies between different lock-classes. The validator maintains a rolling proof that the state and the dependencies are correct. Changes since v2: * Made commit message more clear * Corrected grammer in code comment Tested on Exynos5422 ODROID XU3 board.
