Thank you. I've merged this into a new platform-drivers-x86-simatic-ipc
branch where I'm collecting all the pending platform/x86: simatic-ipc
work.

I'll tag + send a pull-request for Lee later today so that Lee
can merge the (immutable) tag and then apply 2/2 of this series
on top.

Regards,

Hans
