From 0f607cb59efd702630e30e7eeb17adca5b3eda3c Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Wed, 8 Jan 2014 13:44:21 +0800 Subject: [PATCH] ACPICA: Enhance ACPI warning for memory/IO address conflicts. This change improves the warning message when a system address conflicts with an existing operation region. It now emits the region address range in addition to the input (system) address range.
