This is the first of three patches that implement a bit field that
PCI Express device drivers can use to indicate they need a
fundamental reset during error recovery.

By default, the EEH framework on powerpc does what's known as a "hot
reset" during recovery of a PCI Express device.  We've found a case
where the device needs a "fundamental reset" to recover properly.
The current PCI error recovery and EEH frameworks do not support this
distinction.

The attached patch (courtesy of Richard Lary) adds a bit field to
pci_dev that indicates whether the device requires a fundamental
reset during recovery.

These patches supersede the previously submitted patch that
implemented a fundamental reset bit field. 

Please review and let me know of any concerns.

Ok, applied this series to my linux-next branch, it looks pretty
reasonable to me.

For future patches, please cc me, and include the subsystem in the
subject, along with a specific description of the patch, e.g. "PCI: add
PCIe fundamental reset interface", "PCI: document PCIe fundamental
reset", or for arch specific patches, "PCI/powerpc: implement support
for PCIe fundamental reset".

Thanks,
