X-Received-From: 59.151.112.132 Subject: [Qemu-devel] [PATCH 2/3] numa: Remove the numa_post_machine_init function X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: peter.maydell@linaro.org, Dou Liyang , fanc.fnst@cn.fujitsu.com, caoj.fnst@cn.fujitsu.com, stefanha@redhat.com, izumi.taku@jp.fujitsu.com, imammedo@redhat.com, vilanova@ac.upc.edu Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP Current default way of seting the CPUState::numa_node in the numa_post_machine_init() and calling it in vl.c:main() would make the data incorrect in case on cold/hot-plug CPUs. Now, we move it to the qom/cpu.c:cpu_common_realizefn(). So, Here we remove it.
