3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shuah Khan <shuah.k...@hp.com>
commit f2f12b6fc032c7b1419fd6db84e2868b5f05a878 upstream.
The iommu_shutdown callback is not initialized when the AMD
IOMMU driver runs in passthrough mode. Fix that by moving
the callback initialization before the check for
passthrough mode.
