Please keep these in alphabetical order.

Would making the kernel-parameters.txt warning a little bit more informative be a good thing? This should only be used in environments where some other signature verification method is employed.

Also, for future reference, it would be good to have hard numbers to show the boot time improvement in the changelog.

  	module_blacklist=  [KNL] Do not load a comma-separated list of
  			modules.  Useful for debugging problem modules.
