Since commit 854b5338196b1175706e99d63be43a4f8d8ab607 Author: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com> KVM: s390: streamline memslot handling s390 uses the values of the memslot instead of doing everything in the arch ioctl handler of the KVM_SET_USER_MEMORY_REGION. Unfortunately we missed to set the userspace_addr of our memslot due to our s390 ifdef in __kvm_set_memory_region. Old s390 userspace launchers did not notice, since they started the guest at userspace address 0. Because of CONFIG_DEFAULT_MMAP_MIN_ADDR we now put the guest at 1M userspace, which does not work. This patch makes sure that new.userspace_addr is set on s390. This fix should go in quickly. Nevertheless, looking at the code we should clean up that ifdef in the long term. Any kernel janitors?
