Hmm.

A less hacky patch might be to split up "sched.h" into multiple
smaller things and at least get *part* of the way.

A lot of things want "struct task_struct" (and in some cases
thread_info, but that's already split).

Much fewer care about the signal stuff.

And many things probably don't even need the task_struct definition,
and might be perfectly happy with just function calls rather than
having intimate knowledge of the structure layout and an inline
function.
