This patch is essentially being removed by the linux-2.6-xen-ia64-kernel-panics-when-dom0_mem-is-specified_2.patch dma-mapping.h does include the file machvec.h which looks like it might have some swiotlb related code within it. Can someone confirm this change was intended?
Yes. That change was intended. I posted the series of patches to the list and after that posted the following patch since we found an issue with the origianl patch for bz217593. (http://post-office.corp.redhat.com/archives/rhkernel-list/2007- June/msg01830.html) - linux-2.6-xen-ia64-kernel-panics-when-dom0_mem-is-specified_2.patch This patch included "header clean up" portion that removed the changes you pointed out here. As I did on other bug, I am closing this bug as duplication of bz217593. *** This bug has been marked as a duplicate of 217593 ***
