I wanted to keep the split between adding the generalized definitions
that Samuel did here, and my arch specific changes. Thought it'd be
easier to review for people if it was kept this way. But maybe it's a
good idea to just move the asm/kasan-tags changes here too, I'll
rearange the code a bit between these two patches.
