I haven't (yet) changed exc_handler, but I did post that annotation fix as a patch against patch 3 in the series, when actually it should be applied as as fixup to patch 2. I *am* cleaning up exc_handler in patch 3 though, for a more 'warm and fuzzy' experience on int3 rather than dumping the full register set. So I'll repost it from patch 2 against the new tip/x86/boot, including the annotation fix in the right place. Thanks. I haven't yet decided what to do about the unconditional int3. Slightly tempted to suggest we put it in #ifdef CONFIG_DEBUG_ENTRY now I've been reminded that option exists? But we should *also* be doing better testing of kexec-jump, with something like that test case I posted, and adding an int3 into that would be trivial too.
