There is none:

The kernel has _many_ people holding a copyright on part of the kernel,
and there's no ultimate authority except for the COPYING file shipped
with the kernel sources.

The GPL is just a licence, and if you distribute your product to N
countries, this means you can potentially be sued in N countries based
on N different copyright laws.

There are things that are clear. E.g. if you'd have read the COPYING
file shipped with the kernel sources, you could have answered at least
one of your questions yourself.

But the exact borders of what is a "derived work" work and what is not
are not well-defined and therefore unknown unless there have been court
cases in all N countries you are distributing your product to.

Many things have never been challenged in court, and might never be, but
remember that e.g. Harald Welte recently has much success with enforcing
the GPL in cases of obvious violations at for products shipped in
Germany at German courts.

I am not a lawyer, but the distribution alone shouldn't be a problem -
that is similar to what most Linux distributions are doing.
