Does linux use GPL or not??

[Kristiono Setyadi]

I still confused with this GPL or non-GPL.
First, I want to ask about Linux.
Does Linux use a GPL or not?
If someone distributed it (Linux, I mean..) with no GPL, can we called
this a crime?
I am sorry if I can not follow this subject of mailing list.
But I really want to know about the GPL and its friends.. (indeed..).
Thank you.
