Also, this patchset uncovered, IMHO, missing definitions in arch/x86/asm/
topology.h. I posted a patch for that effect here:
https://lore.kernel.org/all/20251117-rneri-topology-cpuinfo-bug-v1-1-a905bb5f91e2@linux.intel.com/
I can repost this patchset along with the patch above if it makes things
easier.
BR,
Ricardo
