This implements the CONFIG_THREAD_INFO_IN_TASK option. With this change: - before thread_info was part of the stack and located at the beginning of the stack - now the thread_info struct is moved and located inside the task_struct structure - the stack is allocated and handled like the major other platforms - drop the cpu field of thread_info and use instead the one in task_struct Signed-off-by: Helge Deller <[email protected]> Signed-off-by: Sven Schnelle <[email protected]>
