So I really think that the _correct_ fix is literally to move the "cli" in the sysenter path down two lines. It doesn't just "hide" the bug, it literally fixes is.
OK, Linus, I find it amazing that you like all my patches, even though I myself think they are wrong:) I still have those two questions however: 1. Does the "later sti" fixes the problem also in case of an NMI? I mean, why can't you just be NMI'ed before you did sti? NMI uses the restore_all too IIRC. 2. How can one be sure there are no more of the like places where the stack is left empty?
