Merge branch 'upstream/core' into upstream/xen
* upstream/core:
xen/panic: use xen_reboot and fix smp_send_stop
Xen: register panic notifier to take crashes of xen guests on panic
xen: support large numbers of CPUs with vcpu info placement
xen: drop xen_sched_clock in favour of using plain wallclock time
pvops: do not notify callers from register_xenstore_notifier
xen: make sure pages are really part of domain before freeing
xen: release unused free memory
