Merge branch 'stable/xen-pciback-0.6.3' into stable/drivers
* stable/xen-pciback-0.6.3: xen/pciback: Have 'passthrough' option instead of XEN_PCIDEV_BACKEND_PASS and XEN_PCIDEV_BACKEND_VPCI 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.

+ help
+ The PCI device backend driver allows the kernel to export arbitrary
+ PCI devices to other guests. If you select this to be a module, you
+ will need to make sure no other driver has bound to the device(s)
+ you want to make visible to other guests.
+
+ The parameter "passthrough" allows you specify how you want the PCI
+ devices to appear in the guest. You can choose the default (0) where
+ PCI topology starts at 00.00.0, or (1) for passthrough if you want
+ the PCI devices topology appear the same as in the host.
+
+ The "hide" parameter (only applicable if backend driver is compiled
+ into the kernel) allows you to bind the PCI devices to this module
+ from the default device drivers. The argument is the list of PCI BDFs:
+ xen-pciback.hide=(03:00.0)(04:00.0)
+
+ If in doubt, say m.
