Note that the # raw_smp_processor_id() is required in order to avoid calling into # lockdep before RCU has declared the CPU to be watched for readers. # # It's safe to call rcu_cpu_starting() in the arch code as well as later # in generic code, as explained by Paul: # # It uses a per-CPU variable so that RCU pays attention only to the # first call to rcu_cpu_starting() if there is more than one of them. # This is even intentional, due to there being a generic # arch-independent call to rcu_cpu_starting() in # notify_cpu_starting(). # # So multiple calls to rcu_cpu_starting() are fine by design. # # Fixes: 4d004099a668 ("lockdep: Fix lockdep recursion") # Signed-off-by: Qian Cai <cai@redhat.com> # Acked-by: Paul E.
