This series is a successor of Lenny's "[PATCH] x86/kvmclock: Stop kvmclocks
for hibernate restore". While reviewing his patch I realized that PV
features teardown we have is a bit messy: it is scattered across kvm.c
and kvmclock.c and not all features are being shutdown an all paths.
This series unifies all teardown paths in kvm.c and makes sure all
features are disabled when needed.

x86/kvm: Fix pr_info() for async PF setup/teardown
x86/kvm: Teardown PV features on boot CPU as well
x86/kvm: Disable kvmclock on all CPUs on shutdown
x86/kvm: Disable all PV features on crash
x86/kvm: Unify kvm_pv_guest_cpu_reboot() with kvm_guest_cpu_offline()

Queuing this patch, thanks.
If the Amazon folks want to provide their Tested-by (since they looked
at it before and tested Lenny's first attempt at using syscore_ops),
they're still in time!
