I do not think making this the default is good idea, because the lz4demo 
utility that you need to actually compress the kernel (used in patch 2) 
is not installed nor available by default on most systems, while gzip 
is. Considering that such a concern was already raised in your v2 
patchset, I am surprised to see this.
