This is part of the confusion I mentioned about this section that needs
to be cleaned up. Basically, for this example, to keep things simple,
we want to use an already-existing branch in the repo. The branch that
was somewhat vaguely chosen for this example was the atom-pc branch. So
this should be the branch specified in the KMACHINE, which my
corrected .bbappend shows, rather than the "yocto/standard/mymachine" in
the example code.
The mention of cgit/cgit.cgi/linux-yocto-3.0 to get the latest commit
strings is correct assuming you're working from master. But this
example is working from edison, where there commits to use are
essentially set in stone and contained in the SRCREVs in the .bb
and .bbappends in the edison branch.
Again, this is part of the confusion in this section that needs cleaning
up.

I got these commits from the kernel .bb and .bbappends captured in the
edison branch, as mentioened above.
