PMINTRMSK handling is now a part of set_rps (and so this line is

Thanks Chris. I will make the changes based on the current nightly code
I think my patch kept up with this, but I too am not sure. In either
case feel free to reuse, copy, or review that one.
I don't think I've mailed out the very latest version, but I am pretty
sure I mailed out after the last painful rebase (and it's tested on
BDW).

Thanks Ben. I will reuse the patches submitted by you
