X-Received-From: 192.55.52.120 Subject: [Qemu-devel] [PATCH v2 2/2] memory-device: break the loop if tmp exceed the hinted range X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: imammedo@redhat.com, david@redhat.com, Wei Yang , mst@redhat.com Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP The memory-device list built by memory_device_build_list is ordered by its address, this means if the tmp range exceed the hinted range, all the following range will not overlap with it. And this won't change default pc-dimm mapping and address assignment stay the same as before this change.
