Hi Keir, The two patches attached are necessary for ia64 in the 3.1-testing tree. We make use of the x86 pci-dma-xen.c in this code based, but our pfn_to_mfn() doesn''t provide the true machine frame. Instead we need pfn_to_mfn_for_dma(). On current upstream, we''ve created our own files for this and we''ve made the corresponding update in ia64/linux-2.6.18-xen.hg. For this backport, the easiest approach seems to be to redefine pfn_to_mfn() for ia64 in this file. The other patch simply backports the addition of the paddr_t typedef.
