You need to pull from our maintenance tree for building over kernel >
3.8, git.xenomai.org/xenomai-2.6. This will be released as 2.6.4 within
a few weeks.

This description does not give the reader any hint about what happened,

reuse the kernel .config shipped with your distro for building the
patched kernel.
