The 'name', 'owner', and 'mod_name' members are redundant with the identically named fields in the 'driver' sub-structure. Rather than switching each instance to specify these fields explicitly, introduce a macro to simplify this. Eliminate further redundancy by allowing the drvname argument to DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from the ID table will be used for .driver.name). Also eliminate the questionable xenbus_register_{back,front}end() wrappers - their sole remaining purpose was the checking of the 'owner' field, proper setting of which shouldn't be an issue anymore when the macro gets used. v2: Restore DRV_NAME for the driver name in xen-pciback.

With Xen changeset 23428 "libxl: Add 'e820_host' option to config file" the E820 as seen from the host can now be passed into the guest. This means that a PV guest can now: - Use the correct PCI I/O gap. Before these patches, Linux guest would boot up and would tell: [ 0.000000] Allocating PCI resources starting at 40000000 (gap: 40000000:c0000000) while in actuality the PCI I/O gap should have been: [ 0.000000] Allocating PCI resources starting at b0000000 (gap: b0000000:4c000000) - The PV domain with PCI devices was limited to 3GB. It now can be booted with 4GB, 8GB, or whatever number you want. The PCI devices will now _not_ conflict with System RAM. Meaning the drivers can load.

Check the returned vector values for any values that are odd or plain incorrect (say vector value zero), and if so print a warning. Also fixup the return values. This patch was precipiated by the Xen PCIBack returning the incorrect values due to how it was retrieving PIRQ values. This has been fixed in the xen-pciback by "xen/pciback: Utilize 'xen_pirq_from_irq' to get PIRQ value" patch.

Stanse found that when pdev is found and has no driver a reference is leaked in pcifront_common_process. So add pci_dev_put there. For the pdev == NULL case, pci_dev_put(NULL) is fine.

This is a port of the 2.6.18 Xen PCI front driver with fixes to make it build under 2.6.34 and later (for the full list of changes: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git historic/xen-pcifront-0.1). It also includes the fixes to make it work properly.
