Ok, I've respun the patches including all of the feedback I've obtained. Again, it's at:
kernel.org:/pub/scm/linux/kernel/git/davem/msiquirk-2.6.git
Greg, I think this stuff is ready to go so if you would pull them in I would really appreciate it.
These changes clean up the handling of the common quirk wherein setting INTX_DISABLE will mistakedly disable MSI generation for some devices.
For devices without that problem, we want to keep the pci_intx() calls in drivers/pci/msi.c because those help protect against devices with the opposite problem. Such devices always generate INTX interrupts even when MSI is enabled, unless INTX_DISABLE is set.
In addition to the Tigon3 cases, I added quirk entries for the SB700/800 SATA chips and the IXP SB400 USB controllers. And as a result of the latter we can remove several AMD full-chipset MSI disable quirks which are no longer necessary.
