From b4cdc4300de6ff7b8b366f23bed17c7d59c8117c Mon Sep 17 00:00:00 2001 From: Dmitri Vorobiev Date: Mon, 28 Apr 2008 03:15:58 +0400 Subject: x86: iommu_sac_force can become static The iommu_sac_force variable is needlessly defined global, and this patch makes it static. Additionally, this variable needs not be explicitly initialized.
