This config item helps getting some useful information when lockup happens. If you want to validate locks then probably you want PROVE_LOCKING... but its overhead is larger.

Anyway the overhead of LOCKUP_DETECTOR is small and multi_v7_defconfig has it enabled so I guess exynos may do it as well.

Could you only fix up the commit msg?
