If a given expedited RCU grace period extends more than the
specified number of milliseconds, a CPU stall warning is printed.
If the RCU grace period persists, additional CPU stall warnings
are printed at more widely spaced intervals. A value of zero
says to use the RCU_CPU_STALL_TIMEOUT value converted from
seconds to milliseconds.
