This one is probably due to a misconfiguration, i.e. you enabled
xenomai, but not a SOC or SOC family which provides an emulated tsc.
A lot of the coded added by the patch is compiled conditionally, so
the fact that a definition for a function is present in the patch
does not necessarily mean that it will be present with your
particular build configuration.
This one indicates a version of Xenomai not ready for Linux 3.18.
Xenomai 2.6.4 for instance can not be compiled with anything more
recent than Linux 3.14. You can use Xenomai 2.6 git if you want
Linux 3.18 support, or if starting a new development, it probably
makes more sense to jump to Xenomai 3.0 directly.
