I tested this branch on Alder Lake, Meteor Lake, Sapphire Rapids,
Broadwell server, Granite Rapids, Icelake server, Sierra Forest, and Rome.
/sys/devices/system/cpu/cpu*/cache is populated correctly.

I ran the tests documented in

https://lore.kernel.org/lkml/20230912032350.GA17008@ranerica-svr.sc.intel.com/

Ricardo
