Hi!
hotplug emulator: Abstract cpu register functions
Abstract function arch_register_cpu and register_cpu, move the implementation
details to a sub function with prefix "__".
each of the sub function has an extra parameter nid, it can be used to register
CPU under a fake NUMA node, it is a reserved interface for cpu hotplug emulation
(CPU PROBE/RELEASE) in x86.
I don't get it. CPU hotplug can already be tested using echo 0/1>
online, and that works on 386. How is this different?
It tests a different code path.
It seems to add some numa magic. Why is it important?
It tests memory and node hotadd too. Memory/node hotadd is a quite problematic
feature and needs all the testing support it can get.
