rcu_dump_cpu_stacks() grab rnp->lock

do_handle_IPI
flush_smp_call_function_queue
rcu_iw_handler spin rnp->lock
deadlock
nmi_cpu_backtrace
wait for 10s or backtrace_mask clear
For arm64 w/o NMI-triggered stack traces, IPI backtrace feature is used,
while in rcu_dump_cpu_stacks(), raw_spin_lock_irqsave_rcu_node() will
grab the rcu_node->lock to protect the rcu_node data used in the
for_each_leaf_node_possible_cpu loop, while the process of backtrace
for the rcu stalled cpu may be longer than expected, causing potential
concurrent issue while someone contending for the same rcu_node->lock.
Like the call trace shown above, rcu_node->lock will not be released
until all the stalled cpus' backtrace finished in nmi_cpu_backtrace()
or 10s timeout in nmi_trigger_cpumask_backtrace(), if there are pending
IPI callbacks in the smp call_single_queue ahead of the ipi_cpu_backtrace
callback contending for the same rcu_node->lock, deadlock will be
inevitable.
To avoid such problems, shorten the critical section that rcu_node->lock
protects to avoid waiting for the backtrace process finish.
