89eeba1594ac641a30b91942961e80fae978f839 is the commit that made the difference:
Cool, thank you for the regression test. Did you doublecheck that everything works fine with 4.8.3 and the patch reverted (assuming that the patch reverts cleanly?)
Yes, I took kernel 4.8.3 and reverted the changes from the commit in question and - at least Altium Designer - works again.
