# commit de5e276c01ab688e5435a6ddef4d82e767aece83
# Author: Christoph Hellwig <hch@lst.de>
# Date:   Fri Nov 30 14:03:18 2018 +0100
# 
#     powerpc/pasemi: use IOMMU bypass instead of forcing dma_direct_ops
#     
#     This should allow the driver to still dip into the iommu for coherent
#     allocation if required.
