[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

[PATCH v2 1/1] s390/spinlock: Provide vcpu_is_preempted

this implements the s390 backend for commit "kernel/sched: introduce vcpu preempted check interface" by reworking the existing smp_vcpu_scheduled into arch_vcpu_is_preempted. We can then also get rid of the local cpu_is_preempted function by moving the CIF_ENABLED_WAIT test into arch_vcpu_is_preemp

[PATCH] s390x/spinlock: Provide vcpu_is_preempted globally

this implements the s390 backend for commit "kernel/sched: introduce vcpu preempted check interface" by simply reusing the existing cpu_is_preempted function. Signed-off-by: Christian Borntraeger --- Martin, Heiko, this patch is a minimal change by not touching all existing users of cpu_is_preem

From: Konstantin Neumoin The following commit 'fad7b7b27b6a (virtio_balloon: Use a workqueue instead of "vballoon" kthread)' has added a regression. Original code with kthread starts the thread inside probe and checks the necessity to update balloon inside the thread immediately. Nowadays the co
