    Linus Torvalds authored
    Pull xen features and fixes from David Vrabel:
    
     - Fully support non-coherent devices on ARM by introducing the
       mechanisms to request the hypervisor to perform the required cache
       maintainance operations.
    
     - A number of pciback bug fixes and cleanups.  Notably a deadlock fix
       if a PCI device was manually uunbound and a fix for incorrectly
       restoring state after a function reset.
    
     - In x86 PVHVM guests, use the APIC for interrupts if this has been
       virtualized by the hardware.  This reduces the number of interrupt-
       related VM exits on such hardware.
