The alternative way to resolve this issue is the following: Save Modules.symvers file generated by OFED kernel modules compilation (drivers/infiniband/Modules.symvers). It can be added to the kernel-ib-devel RPM in the next OFED release. Then in order to compile external module copy this Modules.symvers to the directory where external module is build.
