Hello everyone,

This is an updated version of the DMA-mapping framework redesign
preparation patches, which resolves issues pointed by Linus:

https://lkml.org/lkml/2012/3/23/305

These patches are the first step to clean up a bit dma-mapping api and
introduce support for architecture specific performance improving hints
in a generic way.

For more information please refer to the thread with the first version
of the patches:

https://lkml.org/lkml/2011/12/23/97


Best regards
