That will take some time, but I think I will be able to get some time on
the Oracle's Exadata box.

Attached is a set of eleven RFC patches that split the SWIOTLB library in
two layers: core, and dma_ops related functions.

The set of eleven patches is also accessible on:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb-2.6.git 
swiotlb-rfc-0.4

An example of how this can be utilized in both bare-metal and Xen environments
is this git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git swiotlb-xen-0.4

Sincerely,

Konrad Rzeszutek Wilk
