Indeed the revert is correct. I'm going to apply it in our internal tree and send it out for v5.5-rc* (with stable in CC so it goes to v5.4). Thanks Mehmet!

The fixes for these two are already in v5.5-rc3, [1] and [2] respectively. They are both marked for v5.4, hopefully they'll be included in v5.4.7.
