I think that's a great license.  I still fear that it is not suitable for
kernel documentation, though, especially when we produce documents that
include significant text from the (GPL-licensed) kernel source.  The
result is almost certainly not distributable, and I don't think that's a
good thing.  The GPL is not perfect for documentation, but I don't think
that we have a better alternative for in-kernel docs.
