Let's rewrite it properly using ranges. This fixes certain overflows that are right now possible. E.g. qemu-system-x86_64 -m 4G,slots=20,maxmem=40G -M pc \ -object memory-backend-file,id=mem1,share,mem-path=/dev/zero,size=2G -device pc-dimm,memdev=mem1,id=dimm1,addr=-0x40000000 Now properly errors out instead of succeeding. (Note that qapi parsing of huge uint64_t values is broken and fixes are on the way) "can't add memory device [0xffffffffa0000000:0x80000000], usable range for memory devices [0x140000000:0xe00000000]" Signed-off-by: David Hildenbrand <david@redhat.com> Message-Id: <20181214131043.25071-3-david@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
