Ugh. This doesn't seem to work for me at all. It causes infinite
scrolling of some text that I have no idea about.

I started bisecting (because I thought it might be something else and
I hadn't booted after every pull), but by now the only thing I have
left is ARM and a couple of tiny OF patches .. and the x86 UAPI split.

The split *should* have been safe, since it's mostly a "compile or
not" thing like Peter said, but we had similar problems on other
architectures, when things compiled but didn't actually work due to
missing #define's and #ifdef handling. Things like
architecture-specific macros that have default versions available when
the macro is missing etc.

Now, maybe it's some of the other remaining commits after all, but
from where I am in the bisection it really looks like the uapi patch
is the most likely culprit. So I thought I'd let people know...
