Hi all,

So here we go with the scary patches ;-)

I've been beating in this up and down and we also now have a fairly
nice set of i-g-t tests to check corner-cases of the clflushing and
similar. The mm prefault helper patch is included here for context,
I've submitted that for inclusion through -mm.

Review, comments, flames highly welcome.

Cheers, Daniel
