I just noticed this on the way through, this could likely just
be set to "common-pc", all it really is supposed to be
is a fallback if a machine specific override doesn't work.

(I see that you actually do this in patch 8/10 for 2.6.34 anyway).

And instead of the above, you could just say:

KBRANCH = "yocto/standard/preempt-rt/base"

to have a fallback in place that keeps the fetcher chugging along.
That's all that the KMACHINE default was doing in the end anyway.

Sorry I didn't see this earlier, but seeing it in front of me
here, it jumped out.

The rest looks good.
