[PATCH 1/1] fix a compiling error caused by dmar_disabled

From: Li, Zhen-Hua
Date: Thu Aug 16 2012 - 04:45:59 EST


Fix a compiling error caused by dmar_disabled.

When CONFIG_INTEL_IOMMU is not defined, dmar_disabled is define as 1,
and the codes like "dmar_disabled = 1;" may cause compiling error.
