[PATCH] uml: memory hotplug cleanups
Change memory hotplug to use GFP_NOWAIT instead of GFP_ATOMIC, so that it
will grab memory without sleeping, but doesn't try to use the emergency
pools.
A small list initialization suggested by Daniel Phillips - don't initialize
lists which are just about to be list_add-ed.
