KVM: s390: ucontrol: export page faults to user
This patch introduces a new exit reason in the kvm_run structure named KVM_EXIT_S390_UCONTROL. This exit indicates, that a virtual cpu has regognized a fault on the host page table. The idea is that userspace can handle this fault by mapping memory at the fault location into the cpu's address space and then continue to run the virtual cpu.
