3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jonathan Nieder <[email protected]> commit 8411371709610c826bf65684f886bfdfb5780ca1 upstream. In the spirit of commit 29cf7a30f8a0 ("x86/PCI: use host bridge _CRS info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by default on a board that needs it. This fixes boot failures and oopses introduced in 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci read out res"). The quirk is quite targetted (to a specific board and BIOS version) for two reasons: (1) to emphasize that this method of tackling the problem one quirk at a time is a little insane (2) to give BIOS vendors an opportunity to use simpler tables and allow us to return to generic behavior (whatever that happens to be) with a later BIOS update In other words, I am not at all happy with having quirks like this. But it is even worse for the kernel not to work out of the box on these machines, so...
