From 34ddeb035d704eafdcdb3cbc781894300136c3c4 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Tue, 12 Jun 2012 11:20:19 +0800 Subject: ACPI, APEI, Avoid too much error reporting in runtime This patch fixed the following bug. https://bugzilla.kernel.org/show_bug.cgi?id=43282 This is caused by a firmware bug checking (checking generic address register provided by firmware) in runtime. The checking should be done in address mapping time instead of runtime to avoid too much error reporting in runtime.
