From d903cea3811994d4c4122a0e3ca6d3a197e812e2 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Wed, 15 Mar 2006 14:45:11 +0900 Subject: [PATCH] [IA64] Ignore disabled Local SAPIC Affinity Structure in SRAT According to the ACPI spec, the OSPM must ignore the contents of the Processor Local APIC/SAPIC Affinity Structure in System Resource Affinity Table (SRAT), if its enable flag is cleared. However, ia64 linux refers all of the Processor Local APIC/SAPIC Affinity Structures in SRAT regardless of the enable flag. This is obviously against the ACPI spec. This patch fixes this bug.
