Merge tag 'for-linus-4.9-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen updates from David Vrabel:
"xen features and fixes for 4.9:
- switch to new CPU hotplug mechanism
- support driver_override in pciback
- require vector callback for HVM guests (the alternate mechanism via
the platform device has been broken for ages)"
