[PATCH 0/4]: Resolve MSI vs. INTX_DISABLE quirks, V2.

[David Miller]

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.

These all look great to me, and I've pulled them into my trees.

Thanks a lot for doing this work.

I think they should go to Linus before 2.6.24 is out, any objection from
anyone else with this?

thanks,
