The former case is meant to happen with and\nwithout HOTPLUG_CPU, but without HOTPLUG_CPU, the rcu_offline_cpu\nfunction is no-oped -- while it still gets called, it does not set the\nrcu CPU map.\n\nWith a blank RCU CPU map, grace periods get to tick by completely\noblivious to active RCU read side critical sections.

The offending sequence of events (courtesy\nof Promela/spin, at least after I got the liveness criterion coded\ncorrectly...) is as follows:\n\no\tCPU 0 is in dynticks-idle mode.  Its dynticks_progress_counter\n\tis (say) 10.\n\no\tCPU 0 takes an interrupt, so rcu_irq_enter() increments CPU 0\u0027s\n\tdynticks_progress_counter to 11.\n\no\tCPU 1 is doing RCU grace-period processing in rcu_try_flip_idle(),\n\tsees rcu_pending(), so invokes dyntick_save_progress_counter(),\n\twhich in turn takes a snapshot of CPU 0\u0027s dynticks_progress_counter\n\tinto CPU 0\u0027s rcu_dyntick_snapshot -- now set to 11.  CPU 1 then\n\tupdates the RCU grace-period state to rcu_try_flip_waitack().\n\no\tCPU 0 returns from its interrupt, so rcu_irq_exit() increments\n\tCPU 0\u0027s dynticks_progress_counter to 12.\n\no\tCPU 1 later invokes rcu_try_flip_waitack(), which notices that\n\tCPU 0 has not yet responded, and hence in turn invokes\n\trcu_try_flip_waitack_needed().  This function examines the\n\tstate of CPU 0\u0027s dynticks_progress_counter and rcu_dyntick_snapshot\n\tvariables, which it copies to curr (\u003d\u003d 12) and snap (\u003d\u003d 11),\n\trespectively.\n\n\tBecause curr!\u003dsnap, the first condition fails.\n\n\tBecause curr-snap is only 1 and snap is odd, the second\n\tcondition fails.\n\n\trcu_try_flip_waitack_needed() therefore incorrectly concludes\n\tthat it must wait for CPU 0 to explicitly acknowledge the\n\tcounter flip.\n\no\tCPU 0 remains forever in dynticks-idle mode, never taking\n\tany more hardware interrupts or any NMIs, and never running\n\tany more tasks.  (Of course, -something- will usually eventually\n\thappen, which might be why we haven\u0027t seen this one in the\n\twild.  Still should be fixed!)\n\nTherefore the grace period never ends.  Fix is to make the code match\nthe comment, as shown below.  With this fix, the above scenario\nwould be satisfied with curr being even, and allow the grace period\nto proceed.\n\nSigned-off-by: Paul E.
