The last comment looks a bit strange, unless you consider RZ/V2L to be
part of the RZ/G2L family, so perhaps drop it?

The patch wouldn't apply, but I don't see the problem other than the 
sha hashes are not from a known base. Please send patches against a 
known rcX (rc1 is preferred) unless you have some other dependency. And 
document that dependency.

Anyways, it is applied manually now.
