Thomas Gleixner f6c4fd506c x86/cpu_entry_area: Prevent wraparound in setup_cpu_entry_area_ptes() on 32bit ... The loop which populates the CPU entry area PMDs can wrap around on 32bit machines when the number of CPUs is small. It worked wonderful for NR_CPUS=64 for whatever reason and the moron who wrote that code did not bother to test it with !SMP. Check for the wraparound to fix it.
