[Qemu-devel] [PATCH 1/2] vl: Ensure the numa_post_machine_init func in the appropriate location

[Dou Liyang]

In the numa_post_machine_init(), we use CPU_FOREACH macro to set all
CPUs' namu_node. So, we should make sure that we call it after Qemu
has already initialied all the CPUs.

As we all know, the CPUs can be created by "-smp"(pc_new_cpu) or
"-device"(qdev_device_add) command. But, before the device init,
Qemu execute the numa_post_machine_init earlier. It makes the mapping
of NUMA nodes and CPUs incorrect.

The patch move the numa_post_machine_init func in the appropriate
location.
