These are included in the next-20160218 tag in the linux-next git repo (not
Linus' repo) at:

  git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

You browse this at:

  https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/

If you'd rather, you can also apply the patches yourself to v4.5-rc1.
