This patch series is meant to address some issues I consider to be
low-hanging fruit in regards to memory initialization optimization.

With these two changes I am able to cut the hot-plug memory initialization
times in my environment in half.

v2: Added comments about why we are using __SetPageReserved
Added new config and updated approach used for page init poisoning

mm: Move page struct poisoning to CONFIG_DEBUG_VM_PAGE_INIT_POISON
mm: Create non-atomic version of SetPageReserved for init use
