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.
