powerpc: Rename THREAD_INFO to TASK_STACK
This patch renames THREAD_INFO to TASK_STACK, because it is in fact the offset of the pointer to the stack in task_struct so this pointer will not be impacted by the move of THREAD_INFO. Also make it available on 64-bit, as we'll need it there when we activate THREAD_INFO_IN_TASK.
