Merge tag 'stable/for-linus-3.16-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip into next
Pull Xen updates from David Vrabel:
"xen: features and fixes for 3.16-rc0
- support foreign mappings in PVH domains (needed when dom0 is PVH)
- fix mapping high MMIO regions in x86 PV guests (this is also the
first half of removing the PAGE_IOMAP PTE flag).
- ARM suspend/resume support.
- ARM multicall support"
* tag 'stable/for-linus-3.16-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
x86/xen: map foreign pfns for autotranslated guests
xen-acpi-processor: Don't display errors when we get -ENOSYS
xen/pciback: Document the entry points for 'pcistub_put_pci_dev'
xen/pciback: Document when the 'unbind' and 'bind' functions are called.
xen-pciback: Document when we FLR an PCI device.
xen-pciback: First reset, then free.
xen-pciback: Cleanup up pcistub_put_pci_dev
x86/xen: do not use _PAGE_IOMAP in xen_remap_domain_mfn_range()
x86/xen: set regions above the end of RAM as 1:1
x86/xen: only warn once if bad MFNs are found during setup
x86/xen: compactly store large identity ranges in the p2m
x86/xen: fix set_phys_range_identity() if pfn_e > MAX_P2M_PFN
x86/xen: rename early_p2m_alloc() and early_p2m_alloc_middle()
