Thanks, I'll make that change.

Is it a blocker to the code being pulled in though? I'm
hoping to get this in ASAP for the 3.6 merge window.  As
this isn't a functional defect (I assume __pa() and
virt_to_abs() still achieve the same result), can I get an
OK from you that this isn't a blocker to the code being

I'll submit a patch later to make this change.

Thanks again!
