PING: PATCH: BZ #14557: __kernel_vsyscall unwind info is incorrect

[Roland McGrath]

FYI, the main reason I didn't review that immediately when you posted it
was that you used an attachment instead of the normal way of submitting
a patch.  It's a little thing, but it makes it enough easier for me to do a
quick review that it makes a huge difference in how quickly I get to it
when overloaded (as I have been lately and will be for a while).
