[PATCH 0/9] Rework command handling of AMD IOMMU driver

[Joerg Roedel]

Hi,

this patch-set reworks the command handling in the AMD IOMMU driver. The
functions are better named now and more clearly splitted. Some cases are
also better handled now than before, like the situation of congestion in
the command buffer.

To further increase maintainability the driver now flushes all internal
caches of the IOMMU right after it gets enabled and does not rely on
flushing individual caches before they are used.

Any feedback appreciated.

Regards,

	Joerg
