Wow these are all broken, have I mentioned I hate working on patches in
embargos?

I'll look at these in the morning, it's odd that Linus's tree isn't
showing these same issue, but I might have messed up the arm backports
somehow.  I did test them on using the multi_v7_defconfig configuration
and they built for me locally with gcc.  I'll try to see what is
different here...
