[Qemu-devel] [PATCH 2/3] numa: Remove the numa_post_machine_init functio


From: Dou Liyang
Subject: [Qemu-devel] [PATCH 2/3] numa: Remove the numa_post_machine_init function
Date: Wed, 18 Jan 2017 20:40:06 +0800

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.
