Strange thing, I specially executed make htmldocs before, unexpectedly did not
find these warnings.

I already know why. The literal block is not indented. I will post a new version to
Paul E. McKenney. Excuse me for causing trouble to everyone.

For example:
@@ -398,9 +398,9 @@ In kernels built with CONFIG_RCU_CPU_STALL_CPUTIME=y or booted with
rcupdate.rcu_cpu_stall_cputime=1, the following additional information
is supplied with each RCU CPU stall warning::

-rcu: hardirqs softirqs csw/system
-rcu: number: 624 45 0
-rcu: cputime: 69 1 2425 ==> 2500(ms)
+ rcu: hardirqs softirqs csw/system
+ rcu: number: 624 45 0
+ rcu: cputime: 69 1 2425 ==> 2500(ms)
