    Pull gcc plugins update from Kees Cook:
     "This adds a new gcc plugin named "latent_entropy". It is designed to
      extract as much possible uncertainty from a running system at boot
      time as possible, hoping to capitalize on any possible variation in
      CPU operation (due to runtime data differences, hardware differences,
      SMP ordering, thermal timing variation, cache behavior, etc).
      At the very least, this plugin is a much more comprehensive example
      for how to manipulate kernel code using the gcc plugin internals"
