Hmm. If these have to be maintained by hand, perhaps they can be
BUILD_BUG_ON'd in some appropriate C file? e.g.,
BUILD_BUG_ON(TI_FLAGS != offsetof(struct thread_info, flags));

Other architectures use either DEFINE or OFFSET macros to define
those flags, so that would probably be a better solution if something
more fancy is asked for. That should probably be a separate patch,
though.
