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. Thanks,
Alex
