Why not return that in the low bit of the page address? This is a little more cache efficient, does not leave that odd footprint in the page union and forces the caller to examine the alloc_pages(...P_MEMALLOC) return, making it harder to overlook the fact that it got a page out of reserve and forget to put one back later.
