kvm-4.3-1

s390: timekeeping changes, cleanups and fixes

x86: support for Hyper-V MSRs to report crashes, and a bunch of cleanups.

One interesting feature that was planned for 4.3 (emulating the local
APIC in kernel while keeping the IOAPIC and 8254 in userspace) had to
be delayed because Intel complained about my reading of the manual.
