a9dce3c06e During the stack unwinding process, the return address points to 
the instruction after the call for a normal frame. libunwind uses
IP-1 to lookup unwind information. However, this is not necessary for
interrupted frames such as signal frames (or interrupt frames) in
the kernel context.

This patch handles both cases correctly.
