This may be a case of incredible bad timing, as I haven't kept up on the development of the pdumper. Doing some light reading up on it now, it seems to me that it does the loading from a custom file format instead of writing a native executable. Evidently, this renders any improvements on the unexec code moot, although it's still in the tree, I guess for platforms where the pdumper is not yet fully tested, so I understand the reluctance to spend any more scarce time on it.

Yes, although one could discuss if the concept of ported/unported status still applies in the same way once there is the pdumper. -- Yours sincerely, Roland Kaufmann
