Reserving a free context is both quicker and more likely to fail
(due to limited hardware resources) than setting up a pagetable.
What is more the pagetable init/cleanup code could require
the context to be set up.

Rename a few iommu cache-flush functions that start with
iommu_ to start with amd_iommu now. This is to prevent name
collisions with generic iommu code later on.

With the current IOMMU-API the hardware TLBs have to be
flushed in every iommu_ops->unmap() call-back.
For unmapping large amounts of address space, like it
happens when a KVM domain with assigned devices is
destroyed, this causes thousands of unnecessary TLB flushes
in the IO
Hi,
here is the second version of the patch-set to introduce an
explicit TLB-flushing interface to the IOMMU-API. This
version changed the interface quite a lot compared to the
first version.
This version does not change the semantics of the
iommu_map() and iommu_unmap() functions anymore. The re
