Andy Lutomirski 1354c2fa63 sched/core: Allow putting thread_info into task_struct ...

commit c65eacbe290b8141554c71b2c94489e73ade8c8d upstream.

If an arch opts in by setting CONFIG_THREAD_INFO_IN_TASK_STRUCT,
then thread_info is defined as a single 'u32 flags' and is the first
entry of task_struct.  thread_info::task is removed (it serves no
purpose if thread_info is embedded in task_struct), and
thread_info::cpu gets its own slot in task_struct.

This is heavily based on a patch written by Linus.
