Merge tag 'llvmlinux-for-v3.16' of git://git.linuxfoundation.org/llvmlinux/kernel 

Pull LLVM patches from Behan Webster:
 "Next set of patches to support compiling the kernel with clang.
  They've been soaking in linux-next since the last merge window.

  More still in the works for the next merge window..."
