In order for SIE to interpretively execute STFLE, it requires the real

Before writing the location into the shadow SIE control block, convert

We currently do not run into this bug because the lower 31 bits are the
same for virtual and physical addresses.

So it's not a bug (yet) :)

But certainly the right thing to do and more future-proof.
