I've had a quick look at [1], and IIUC that's a hard prerequisite for
livepatching, as without it the kernel *will* crash if it attempts a
late module relocation.
Given that, I don't think that we can take patch 2 until Will's comments
on [1] have been addressed, but I think that we could take patch 1 (with
fixups) as per my other reply.
Mark.
