Message-ID: <1221670377-19295-20-git-send-email-joerg.roedel@amd.com> Date: Wed, 17 Sep 2008 18:52:53 +0200 From: Joerg Roedel <joerg.roedel@....com> To: linux-kernel@...r.kernel.org CC: iommu@...ts.linux-foundation.org, Joerg Roedel <joerg.roedel@....com> Subject: [PATCH 19/23] AMD IOMMU: free domain bitmap with its allocation order The amd_iommu_pd_alloc_bitmap is allocated with a calculated order and freed with order 1. This is not a bug since the calculated order always evaluates to 1, but its unclean code. So replace the 1 with the calculation in the release path.
