Hi, Any thoughts on tightening this up and adding some warnings for this? Motivated by a bug I added to powerpc which broke disabled-disable callers. Not that I necessarily want archs to be able to depend on this, it would always be better to be tolerant. But it seems a risky pattern for random code to be using. This still fires off quite a few warnings on powerpc, and I haven't test booted any other arch so probably wouldn't ask to upstream patch 3 just yet, but if there are no objections to the idea I might do a bit more work on it.
