Remove _enter_critical_mutex() and _exit_critical_mutex(). They are unnecessary wrappers, respectively to mutex_lock_interruptible() and to mutex_unlock(). They also have an odd interface that takes an unused argument named pirqL of type unsigned long. Replace them with the in-kernel API. Ignore return values as it was in the old code.
