  xen/pciback: Remove the DEBUG option.
  xen/pciback: Drop two backends, squash and cleanup some code.
  xen/pciback: Print out the MSI/MSI-X (PIRQ) values
  xen/pciback: Don't setup an fake IRQ handler for SR-IOV devices.
  xen: rename pciback module to xen-pciback.
  xen/pciback: Fine-grain the spinlocks and fix BUG: scheduling while atomic cases.
  xen/pciback: Allocate IRQ handler for device that is shared with guest.
  xen/pciback: Disable MSI/MSI-X when reseting a device
  xen/pciback: guest SR-IOV support for PV guest
  xen/pciback: Register the owner (domain) of the PCI device.
  xen/pciback: Cleanup the driver based on checkpatch warnings and errors.
  xen/pciback: xen pci backend driver.
  xen: tmem: self-ballooning and frontswap-selfshrinking
  xen: Add module alias to autoload backend drivers
  xen: Populate xenbus device attributes
  xen: Add __attribute__((format(printf... where appropriate
