Help text

Select this to move thread_info off the stack into task_struct. To make this work, an arch will need to remove all thread_info fields except flags and fix any runtime bugs.

One subtle change that will be needed is to use try_get_task_stack() and put_task_stack() in save_thread_stack_tsk() and get_wchan().
