Subject: [RFC 00/11] select_idle_sibling rework

Hi all,

This is all still very preliminary and could all still go up in flames (it has
only seen hackbench so far). This is mostly the same code I posted yesterday,
but hopefully in a more readable form.

This fixes the SIS_PROP as per the outline here:

  https://lkml.kernel.org/r/20180425153600.GA4043@hirez.programming.kicks-ass.net

and Rohit's suggestion of folding the iteration loops.

For testing I would suggest to ignore the last 3 patches, those are purely
cleanups once the first lot is found to actually work as advertised.
