Hey guys,

I'm new to contributing to GNU projects, but... I'm guessing I send
commits through here? Would appreciate some sort of note on the
procedure on the website

I noticed that your matrix multiplication code had bad cache
performance due to a misordering of a loop. In a replicated version of
my change, I saw about 20% performance gains on my AMD FX CPU.

Do let me know if this is not the correct contribution procedure.
