This must have been messed up while merging, the intention was
clearly to unlock there.

Hi,
I've got a current (pulled today) kernel running on a Xeon E5-2648L CPU
on an Intel motherboard, and I'm trying to get VT-d working without much
success.
lspci -vv (version 3.1.4) doesn't show anything related to IOV.
(Full output below.) Since

Minus has more precedence than left shift.
"1 << get_order(size) - order;" is equivalent to 1 << (get_order(size) - order
This function is called from enable_iommus(), which in turn is used
from amd_iommu_resume().
