Okay... I thought that it will be easier to have it done in generic 
code, if You don't
think so, then I give up and we will add it in all drivers requiring 
such memory regions.

What about patch 3/4 and 4/4? Would it be possible to have your ack to 
get them merged?
Right now patch 4/4 depends on changes from akpm tree, so it will be 
best to merge them
to akpm tree.

Best regards
