From: Xie XiuQi <xiexiuqi@huawei.com>
Commit 6bfc09e2327d ("rcu: Provide RCU CPU stall warnings for tiny RCU") moved the rcu_cpu_stall_timeout module parameter from rcutree.c to rcupdate.c, but failed to update Documentation/RCU/stallwarn.txt. This commit therefore repairs this omission.
commit 96224daa16d6 ("documentation: Update sysfs path for rcu_cpu_stall_suppress") updated the path for rcu_cpu_stall_suppress, but failed to update for rcu_cpu_stall_timeout.
