Andy Lutomirski 0061b518b1 uprobes, x86: Fix _TIF_UPROBE vs _TIF_NOTIFY_RESUME ... commit 82975bc6a6 upstream. x86 call do_notify_resume on paranoid returns if TIF_UPROBE is set but not on non-paranoid returns. I suspect that this is a mistake and that the code only works because int3 is paranoid. Setting _TIF_NOTIFY_RESUME in the uprobe code was probably a workaround for the x86 bug. With that bug fixed, we can remove _TIF_NOTIFY_RESUME from the uprobes code.
