Carsten Otte 2668dab794 KVM: s390: Fix memory slot versus run - v3 ... This patch fixes an incorrectness in the kvm backend for s390. In case virtual cpus are being created before the corresponding memory slot is being registered, we need to update the sie control blocks for the virtual cpus. *updates in v3* In consideration of the s390 memslot constraints locking was changed to trylock. These locks should never be held, as vcpu's can't run without the single memslot we just assign when running this code. To ensure this never deadlocks in case other code changes the code uses trylocks and bail out if it can't get all locks. Additionally most of the discussed special conditions for s390 like only one memslot and no user_alloc are now checked for validity in kvm_arch_set_memory_region.
