Hey Matt,

I was wondering if you're on track to queue up your -next branch for 3.17?

If so, could you please include $subject? And if you don't mind, could
you squash the following fixup into "efi: efistub: Convert into static
library" as well?

diff --git a/arch/arm64/kernel/Makefile b/arch/arm64/kernel/Makefile

Much appreciated,

Cheers,
