From f3ac84324fd949f671e6cf5620add5de02498386 Mon Sep 17 00:00:00 2001 From: Daniel Ritz Date: Tue, 14 Nov 2006 02:03:25 -0800 Subject: [PATCH] fix via586 irq routing for pirq 5 Fix interrupt routing for via 586 bridges. pirq can be 5 which needs to be mapped to INTD. But currently the access functions can handle only pirq 1-4. this is similar to the other via chipsets where pirq 4 and 5 are both mapped to INTD.
