We can use raw_smp_processor_id() here because the processor ID is only used for debug output and may therefore be preemption-unsafe. Signed-off-by: Joachim Fenkes <redacted> --- This is the same patch, but with smp_processor_id() replaced by raw_smp_processor_id(), as kindly pointed out to me by Nathan.
