3.8.13.4 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Jed Davis <j...@mozilla.com>
With this change, we no longer lose the innermost entry in the user-mode
part of the call chain. See also the x86 port, which includes the ip,
and the corresponding change in arch/arm.
