Merge tag 'kvm-s390-20140429' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-next
1. Guest handling fixes The handling of MVPG, PFMF and Test Block is fixed to better follow the architecture. None of these fixes is critical for any current Linux guests, but let's play safe. 2. Optimization for single CPU guests We can enable the IBS facility if only one VCPU is running (!STOPPED state). We also enable this optimization for guest > 1 VCPU as soon as all but one VCPU is in stopped state. Thus will help guests that have tools like cpuplugd (from s390-utils) that do dynamic offline/ online of CPUs. 3. NOTES There is one non-s390 change in include/linux/kvm_host.h that introduces 2 defines for VCPU requests: define KVM_REQ_ENABLE_IBS 23 define KVM_REQ_DISABLE_IBS 24
