Both register_memory_notifer and unregister_memory_notifier are global and
declared so in linux/memory.h. Update the HOTPLUG specific definitions to
match. This fixes a compile warning when HOTPLUG is enabled.

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

We can't export a static struct to modules.

This basically keeps up from having to extern __kmalloc_section_memmap().
The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that
header gets hard to work with, because it needs some arch-specific macros.
Just stick it in here for now, instead of creating another header.

This adds generic memory add/remove and supporting functions for memory
hotplug into a new file as well as a memory hotplug kernel config option.
Individual architecture patches will follow.
For now, disable memory hotplug when swsusp is enabled. There's a lot of
churn there right now. We'll fix it up properly once it calms down.
