We fixed a bunch of similar issues where code was located in the .data
section for ease of use from assembly code.  See commit b4e61537 and
d0776aff for example.

Thanks hey some assembly fun for the holidays :) I also need to check what
all gets relocated to SRAM here.

In any case, seems like the $subject patch is too intrusive for v4.5 at
this point.

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.

Ugh, sorry for the breakage.

Should this patch stay as-is and people will fix their various RODATA
failures during the next devel window, or should I remove the "default
y if CPU_V7"?

I think we'll keep it as-is, and have another go with it at -rc1 time,
when people have ample chance to then queue up fixes.

They'll have had notice of it, so there's no excuse folk can't work on
the problem in the mean time.  (But, of course, they won't...)
