From 6514fa9654088de79c80454d320e228c624a2ec4 Mon Sep 17 00:00:00 2001 From: David Miller Date: Tue, 15 May 2007 01:46:19 -0700 Subject: [PATCH] [PATCH] SPARC64: Be more resiliant with PCI I/O space regs. If we miss on the ranges, just toss the translation up to the parent instead of failing. Signed-off-by: David S.
