    rcu: Remove conditional compilation for RCU CPU stall warnings · a00e0d71

    The RCU CPU stall warnings can now be controlled using the
    rcu_cpu_stall_suppress boot-time parameter or via the same parameter
    from sysfs.  There is therefore no longer any reason to have
    kernel config parameters for this feature.  This commit therefore
    removes the RCU_CPU_STALL_DETECTOR and RCU_CPU_STALL_DETECTOR_RUNNABLE
    kernel config parameters.  The RCU_CPU_STALL_TIMEOUT parameter remains
    to allow the timeout to be tuned and the RCU_CPU_STALL_VERBOSE parameter
    remains to allow task-stall information to be suppressed if desired.
