Yeah, I wish you would not have done that :-( I really don't like those
patches. I just don't much believe in that dynamic validation thing, and
doubly not for the patches you did pick not including any actual
rationale for it.


Also, the patches very much do not apply to tip/objtool/core,
specifically Josh recently reworked the reloc stuff quite dramatically.
