[PATCH v2 0/1] s390 preparation for vcpu preempted check

This patch should enable s390 support for the upcoming vcpu preempt check support, but it should compile and work fine without that patch set as well. Christian Borntraeger (1): s390/spinlock: Provide vcpu_is_preempted arch/s390/include/asm/spinlock.h | 3 +++ arch/s390/kernel/smp.c
