[Xen-devel] [PATCH 2/2] Share VT-d code between x86 and IA64
This patch allocates VT-d page table pgd, root_entry, iremap and qinval from domheap rather than xenheap, and gets rid of structure page_info in iommu.c.

Please merge and re-send. I applied patch 1/2 as > changeset 17409.I''ve now reverted it as it breaks the build without patch 2/2. Please send a version of patch 1/2 which works by itself without 2/2. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
