Subject: [patch v5 00/19] x86/cpu: Rework topology evaluation

This is a follow up on V4 of this work:

  https://lore.kernel.org/all/20230814085006.593997112@linutronix.de

and contains only the not yet applied part which reworks the CPUID
parsing. This is also preparatory work for the general overhaul of APIC ID
enumeration and management.

Changes vs. V4:

  - Add DIEGRP level explicitly

This applies on Linus tree and is available from git:

  git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git topo-cpuid-v5

Thanks,

	tglx
