Pull s390 fix from Alexander Gordeev:

 - s390 selects GENERIC_LOCKBREAK when PREEMPT is enabled to tackle an
   old compile error that no longer exists. Since recently PREEMPT is
   always enabled, this LOCKBREAK config causes massive performance
   regressions.

   Remove GENERIC_LOCKBREAK from s390 Kconfig to fix the degradation.
