Running softirqs enables # local irqs, which can replay pending interrupts causing recursion in # replay_soft_interrupts. This abridged trace shows how this can occur: # # ! NIP replay_soft_interrupts # LR interrupt_exit_kernel_prepare # Call Trace: # interrupt_exit_kernel_prepare (unreliable) # interrupt_return # --- interrupt: ea0 at __rb_reserve_next # NIP __rb_reserve_next # LR __rb_reserve_next # Call Trace: # ring_buffer_lock_reserve # trace_function # function_trace_call # ftrace_call # __do_softirq # irq_exit # timer_interrupt # ! replay_soft_interrupts # interrupt_exit_kernel_prepare # interrupt_return # --- interrupt: ea0 at arch_local_irq_restore # # This can not be prevented easily, because softirqs must not block hard # irqs, so it has to be dealt with. # # The recursion is bounded by design in the softirq code because softirq # replay disables softirqs and loops around again to check for new # softirqs created while it ran, so that's not a problem. # # However it does mess up interrupt replay state, causing superfluous # interrupts when the second replay_soft_interrupts clears a pending # interrupt, leaving it still set in the first call in the 'happened' # local variable. # # Fix this by not caching a copy of irqs_happened across interrupt # handler calls. # # Fixes: 3282a3da25bd ("powerpc/64: Implement
