SVN rev 219737 on 2011-03-18 12:13:04Z by jhb
Fix a few issues with HyperTransport devices and MSI interrupts:
- Always enable the HyperTransport MSI mapping window for HyperTransport
to PCI bridges (these show up as HyperTransport slave devices).
The mapping windows in PCI-PCI bridges are enabled by existing code
in the PCI-PCI bridge driver as MSI requests propagate up the device
tree, but Host-PCI bridges don't really show up in that tree.
- If the PCI device at domain 0 bus 0 slot 0 function 0 is not a
HyperTransport device, then blacklist MSI on any other HT devices in
the system. Linux has a similar quirk.
