You will need an ipipe-enabled kernel anyways. Prepare kernel will just
install the xenomai-bits.
If you do not want to use an ipipe-kernel from upstream you can
rebase/merge the ipipe branch (in your case 4.9.y) onto/into your
kernel. All that should be under version control. Prepare-kernel is a
build step and should be done on a clean working copy when building.
