Christian Borntraeger bb223055b9 s390-ccw-virtio: allow for systems larger that 7.999TB 
KVM does not allow memory regions > KVM_MEM_MAX_NR_PAGES, basically
limiting the memory per slot to 8TB-4k. As memory slots on s390/kvm must
be a multiple of 1MB we need start a new memory region if we cross
8TB-1M.

With that (and optimistic overcommitment in the kernel) I was able to
start a 24TB guest on a 1TB system.
