Description Keiichiro Tokunaga 2007-06-01 20:26:26 UTC

Description of problem:
Need to change to include a generic swiotlb.h for ia64.  Without this fix, 
thrid party driver cannot be compiled.

cset#14056 fixes the issue.

Comment 2 RHEL Program Management 2007-06-18 21:10:47 UTC

This request was evaluated by Red Hat Kernel Team for inclusion in a Red
Hat Enterprise Linux maintenance release, and has moved to bugzilla 
status POST.

Comment 6 Mike Gahagan 2007-09-25 19:07:29 UTC

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?

Comment 7 Keiichiro Tokunaga 2007-09-25 19:40:31 UTC

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.
