Subject: [Qemu-devel] [PATCH v2] vl: Ensure the cpu_synchronize_all_post_init() in the appropriate location
Date: Wed, 18 Jan 2017 21:39:55 +0800

At the Qemu initialization, we call the cpu_synchronize_all_post_init()
to synchronize All CPU states to KVM in the ./vl.c::main().

Currently, it is called before we initialize the CPUs, which created by
"-device" command, So, these CPUs may be ignored to synchronize.

The patch moves the numa_post_machine_init func in the appropriate
location to make sure that all the CPUs has already been created
when it is called.

Signed-off-by: Dou Liyang <address@hidden>

Change log v1-> v2:
1. Split it from 
2. Rewrite the log.
