[PATCH] x86_64: add x86-64 support for memory hot-add
Add x86-64 specific memory hot-add functions, Kconfig options,
and runtime kernel page table update functions to make
hot-add usable on x86-64 machines. Also, fixup the nefarious
conditional locking and exports pointed out by Andi.
Tested on Intel and IBM x86-64 memory hot-add capable systems.
