Hi!

This is the follow up to:

  https://lore.kernel.org/lkml/20230717223049.327865981@linutronix.de

which addresses the review feedback and some minor 0day-robot fallout.

TLDR: This cleans up accrued and partially unused gunk in order to convert
the APIC callbacks to static calls.

The changes vs. V1:

  - Fixed the minor fallout reported by Michael and Peter

  - Mopped up XEN/PV even more - Juergen

  - Fixed up a place which still wrote into mp_lapic_addr directly in
    mpparse

  - Addressed 0day fallout on 32bit with KVM guest enabled and local APIC
    disabled. Sigh!

The series is also available from git:

  git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git apic-static-call-v2

Thanks,

	tglx
