I've received a number of mails about where to obtain the latest versions of Linux while the tarballs/diffs are still missing from kernel.org.
If you know how to use git, then you already know how to get the latest stable kernels, so for everyone else, I'm putting the interdiffs of stable versions up in http://grsecurity.net/~spender/
So for instance, start with:
http://www.kernel.org/pub/linux/kernel/ ... .4.tar.bz2
then apply:
http://grsecurity.net/~spender/patch-3.0.4-6
and then:
http://grsecurity.net/~spender/patch-3.0.6-7
to update to Linux 3.0.7
