Merge tag 'stable/for-linus-4.1-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip

Pull xen features and fixes from David Vrabel:

 - use a single source list of hypercalls, generating other tables etc.
   at build time.

 - add a "Xen PV" APIC driver to support >255 VCPUs in PV guests.

 - significant performance improve to guest save/restore/migration.

 - scsiback/front save/restore support.

 - infrastructure for multi-page xenbus rings.

 - misc fixes.
