Rather fragile, but so was the old code and I see that IN_SIGTRAMP()
has been deprecated, which is a good thing. Perhaps this code will
vanish altogether in the future. On ia64, it'd be better to use
libunwind to check whether a frame is a signal-trampoline frame (via
unw_is_signal_frame()). But for now, I hope/assume your patch will be
applied.
Thanks,
