Makes it general to the hotplug operation, renaming it at memplug_context
and move its define in the corresponding header.
There is no functional change introduced by this patch
I do not want to nit picking on naming but we want to look at this from
the initialization POV rather than hotplug. So....

Sounds good too.
What about its definition's place, in include/mm/zone.h as David suggested ?
