From: Joerg Roedel Date: Wed, 17 Sep 2008 10:19:58 +0000 (+0200) Subject: AMD IOMMU: free domain bitmap with its allocation order X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d58befd3a0110c93d70756537b4d01d05a9e6e12;p=linux-beck.git 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.
