It can be used to get a stack trace of the current thread. Note that this works by walking frame pointers and will not produce anything useful if an application is compiled with the frame pointers omitted. The stack base and end addresses have to be provided as arguments and are used to check that the frame pointers fall within that range. These values are thread specific and can be retrieved with get_thread_info(). No other sanity checks (like checking for loops in the linked list) are done. This is a simplified rewrite of the stack trace code from the kernel debugger. As this code is common to x86 and x86_64 but is not generic across architectures I introduced x86_common as a directory to put such sources.
