This was largely okay but there are exceptions. There was one on an embedded platform which was fixed via firmware and now bko#14124 reports it on a HP DL320. http://bugzilla.kernel.org/show_bug.cgi?id=14124 I still think this isn't something libata drivers should be caring about (the only ones which are calling pci_intx() explicitly are libata ones and one other driver) but for now reverting the change seems to be the right thing to do.
