Hi Bruce,
I've added recipes-kernel to use edf branch and cfg.
FYI: your email keeps bouncing from the linux-yocto mailing list,
check to be sure you signed up with your gmail account, I keep
approving them for now :)

We don't need this fragment in recipe space, it's already in the
kernel tree itself.
I've already sent the pull request for the meta SRCREVs to be updated,
so it's available for all builds now.

These are already taken care of by meta-intel, we don't need to
duplicate them here.

We don't need these two KMACHINE lines, this is the default.
