Hi Denys,

Thanks for resurrecting this, I am still interested here, we have been
using this patch in our PPC & ARM32 systems since it was posted.

Benjamin gave some feedback that some small style issues might need
changing, but I never agitated enough to get feedback from mm or core,
which is really what is needed for this patch..
