This is a two-part patch series:

Part1: 1-4 :
Introduce a workaround for the current AMD IOMMU perf initialization issue
in some existing KV and CZ platforms, where it fails to write to IOMMU
perf counter as reported by Andreas Hartmann here
(http://comments.gmane.org/gmane.linux.kernel.pci/49147).

Okay, these 4 patches fix the issue, but they also refactor the code and
so a lot more. They are not suitable for stable kernels, so to just fix
the issue I take the small patch I extracted from yours and posted
previously. I retains your authorship, hope that is fine with you.

You can rebase these patches on-top of that minimal fix.

I'll do that and send out V6.

Thanks,
Suravee
