Hi all,
I see Joerg has backported it to sles12 in the commoent of novel
bugzilla 856382, so I will only backport it to redhat el.
Thanks

Hi,
as David Woodhouse pointed out, my fixes and cleanups for
the original patch-set turned out to be a complete rewrite.
So to have a cleaner history of the feature and to make
backporting easier, here is a rewrite of my changes based on
v4.1-rc7.
Some additional issues have been fixed by this rewrite, like
a kdump-kernel boot panic with 'iommu=pt' and support for
copying the extended root-entry and context table formats
has been added.
I plan to rebuild the x86/vt-d branch of the iommu tree with
these patches.
Regards,
Joerg
