Linux kernel with clang. :)

Seems like building the Linux kernel with llvm is all the rage, so I
thought I'd give it a go on ppc64le today. A number of issues still to
sort through, and llvm did uncover some impressive kernel bugs
like http://patchwork.ozlabs.org/patch/404876/
<http://patchwork.ozlabs.org/patch/404876/> , but it boots:
