Given Christmas and an unknown time between that and the merge window
actually opening, I decided Tuesday would be the last day I take any
patches into my tree - and today would be the day that I drop anything
that causes problems.

So, I've already dropped this, so tomorrow's linux-next should not have
this change.

You'll still see breakage if people enable RODATA though, but that's no
different from previous kernels.
