I redid the patch again, after realising that the non-physical-page path
was for supporting VirtualBox 3.0 and older on the host, which we have
not tested or supported for a long time.  Therefore
VbglR0CanUsePhysPageList() could be removed altogether.

Hans, I kept your signed-off-by despite my changes, I hope that is fine.

Yes that is fine.

The changes I committed are also attached to this message.

It seems that you've introduced a bug there. You've removed the

err = RT_FAILURE(err) ? -EPROTO : 0;

Line after the VbglR0SfWritePhysCont() call, but that call returns
a VBox status code and sf_reg_write should return a negative
errno value on error.
