Subject: [patch V2 00/22] x86/topology: More cleanups and preparatory work

This is a follow up to and a breakout from:

  https://lore.kernel.org/all/20230807130108.853357011@linutronix.de

It's mostly mopping up technical debt and preparing for the actual APIC ID
management rework, which is required to handle asymmetric configurations
like P/E systems correctly.

Changes vs. the original series:

  - Split out the preparatory work

  - Address review feedback (Andy)

It applies on top of:

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

and is available from git:

  git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git topo-cleanup-v2

Thanks,

	tglx
