You should probably re-organize the set so that these definitions are in place prior to the addition of the call sites though (just to avoid inadvertent build breaks if someone tries to turn AUTO_RESERE on in the middle of this commit series. And I still think making this a definition in asm-generic might be worth while, since it seems to be the same or simmilar for all arches.
