Subject: [PATCH 0/3] Add and use get_cpu_cacheinfo_level()

[get_maintainer.pl is vague about who owns <linux/cacheinfo.h>
 to I've scattershooted some of the folks that committed changes
 for this file]

This helper function came up in discussion of the resctrl patches
for Sub-NUMA Cluster (SNC) support. Reinette pointed out[1] that there
are already two places where it would clean things up by avoiding
open coding. The SNC patches will add two additional call sites.

So rather than have this jammed up as part of the SNC series, I'm
posting it as a simple standalone cleanup.
