Comment 5 for bug 1758910

Every one of these except the last three (the ones from the powerpc tree) are on the other bug, so I'm going to commit them as part of that one. That bug also includes the additional fix I identified.

The last one, a5d4b5891c2f1f865a2def1eb0030f534e77ff86, does not apply and seems to be missing prerequisite patches. I'm going to hold off applying these three patches, please advise of the full list of patches necessary to apply this commit. Thanks!
