From 112f1fc08d0b3f81c594af617d88c0db6ce0873c Mon Sep 17 00:00:00 2001 From: Chen Gong Date: Fri, 7 Dec 2012 11:50:02 -0800 Subject: [PATCH] ACPI, APEI, EINJ: Add missed ACPI5 support for error trigger table To handle error trigger table correctly, memory region must be removed from request region. We had a series of patches to do this culminating in: commit b4e008dc5 ACPI, APEI, EINJ, Refine the fix of resource conflict but when ACPI5 support was added, we missed updating this area. So when using EINJ table on an ACPI5 enabled machine, we get following error: APEI: Can not request [mem 0x526b80000-0x526b80007] for APEI EINJ Trigger registers Fix this by checking for the acpi5 case and using the same code that was added earlier.
