From: Joerg Roedel <jroe...@suse.de>
The map and unmap functions of the IOMMU-API changed their
semantics: They do no longer guarantee that the hardware
TLBs are synchronized with the page-table updates they made.
To make conversion easier, new synchronized functions have
been introduced which give these guarantees again until the
code is converted to use the new TLB-flush interface of the
IOMMU-API, which allows certain optimizations.
But for now, just convert this code to use the synchronized
functions so that it will behave as before.
