Well, that one has my patches on top while we agreed with Patrik to
have the opposite order in the end, since I think that makes more sense
for bisectability: Patrik's change to move DC6 enabling earlier might
reveal some issues that are supposed to be fixed in my patchset. Anyway
the end result should be the same so hopefully that branch was useful
for testing.
