Hi!
This is the follow up to:
https://lore.kernel.org/lkml/[email protected]
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

This series works fine on a couple of systems that I have (but they
aren't 32-bit).
Please feel free to add:

With the changes suggested for patches 16 and 50 this series seems to work
fine for Xen PV (dom0 and domU).
Juergen
