[PATCH] ARM: 2761/1: OProfile: Add call graphing support for arm

Patch from Richard Purdie

Add functions to generate backtraces of both kernel and user processes
which allows oprofile's call graphing functionality to be used on arm.
This requires unstripped binaries/libs which use a frame pointer.
