Thanks, Stephen.  Diana has posted a 32bit build fix which I've merged,
maybe that was the error.  Also Diana's series in my branch is currently
dependent on fsl-bus support in GregKH's char-misc-next branch.  Looking
at the log from the successful build, I wonder if our branches are just
in the wrong order (vfio/next processed on line 341, char-misc-next
processed on 387).  I don't know if you regularly re-order for this
sort of thing, otherwise it should work out when Greg's branch gets
merged, but testing sooner in next would be preferred.  Thanks,

Alex
