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
