Date: Thu, 4 Dec 2008 18:31:41 +0100 From: Joerg Roedel <joerg.roedel@....com> To: avi@...hat.com, mingo@...hat.com, dwmw2@...radead.org, gregkh@...e.de, weidong.han@...el.com CC: iommu@...ts.linux-foundation.org, linux-kernel@...r.kernel.org, kvm@...r.kernel.org, Joerg Roedel <joerg.roedel@....com> Subject: [PATCH 04/19] AMD IOMMU: make dma_ops_free_pagetable generic Impact: change code to free pagetables from protection domains The dma_ops_free_pagetable function can only free pagetables from dma_ops domains. Change that to free pagetables of pure protection domains.
