Let me try asking my question again, since some of the details from
the original email have been trimmed.

Here's what root directory of the Beaglebone "kernel" git repo (3.8
branch) looks like:

        <lots of patches>
    <lots of other directories with patches>

The patch.sh script clones the Linus kernel and patches it when you run it.

Now, regarding Buildroot, there's an option for specifying the Linux
kernel via a git reference, but the expectation is that you'll be
getting Linux source code. There are also ways of applying patches to
a Linus kernel. The problem that I am trying to ask about is how best
to deal with the 600+ patches that are contained in beagleboard/kernel
patch tree.

Does this make more sense now?
