Subject: [PATCH 2/6] AMD IOMMU: remove unnecessary set_bit_string
Date: Thu, 3 Jul 2008 19:35:07 +0200 [thread overview]
Message-ID: <1215106511-12915-3-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1215106511-12915-1-git-send-email-joerg.roedel@amd.com>
The set_bit_string call in the address allocator is not necessary because its
already called in iommu_area_alloc().
