[RFC PATCH 0/2] sched/topology: Get rid of overlapping groups

Hi folks,

My keyboard still hasn't been taken away from me, so I went down and did what I
was rambling about in [1].

The preemptive degeneration check is the worst wart, but I think I'll have to
sleep on it before I can figure out a better way.

Something tells me the increase in group numbers isn't going to make me any
friends, so I've included 3/2 which is Barry's approach (with the subset check
condensed in a single spot).

Cheers,
Valentin
