Cleanups related to kvm_set_memory_region(), salvaged from similar patches that were flying around when we were sorting out KVM_SET_USER_MEMORY_REGION2. And, hopefully, the KVM-internal memslots hardening will also be useful for s390's ucontrol stuff (https://lore.kernel.org/all/Z4FJNJ3UND8LSJZz@xxxxxxxxxx). v2: - Keep check_memory_region_flags() where it is. [Xiaoyao] - Rework the changelog for the last patch to account for the change in motiviation. - Fix double spaces goofs. [Tao] - Add a lockdep assertion in the x86 code, too.
