Use common arch_stack_walk infrastructure to avoid duplicated code and avoid taking care of the stack storage and filtering. Common code also uses try_get_task_stack/put_task_stack when needed which have been missing in our code, which also solves potential problem for us. Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
