Add kernel support for oprofile callgraphs on AVR32
This patch adds backtracing capability to oprofile profiling in kernel and user mode on AVR32. This is done by going through the frames on the stack and adding oprofile traces for all return addresses. The code being profiled has to be compiled with frame pointers to make this work.
