Public bug reported:
There's already a check to ensure pinned CPUs are unpinned and vice
versa, but none to ensure the CPUs are in the known set. This could lead
to an invalid system state and emergent bugs.
I noticed this via code inspection during Liberty. I don't know if it's
possible to hit externally but it seems like a potential bug. John
Garbutt encouraged me to open this for advertising.
