x86/intel_rdt/cqm: Improve limbo list processing
The regression was introduced as of v4.14-r1 and still exists with
current mainline. The trace with v4.15-rc7 is in comment #44.
I was hoping to get your feedback, since you are the patch author. Do
you think gathering any additional data will help diagnose this issue,
or would it be best to submit a revert request?
