      slub: Remove CONFIG_CMPXCHG_LOCAL ifdeffery · 1759415e
      Christoph Lameter authored
      Remove the #ifdefs. This means that the irqsafe_cpu_cmpxchg_double() is used
      everywhere.
      
      There may be performance implications since:
      
      A. We now have to manage a transaction ID for all arches
      
      B. The interrupt holdoff for arches not supporting CONFIG_CMPXCHG_LOCAL is reduced
      to a very short irqoff section.
      
      There are no multiple irqoff/irqon sequences as a result of this change. Even in the fallback
      case we only have to do one disable and enable like before.
