Public bug reported:

Binary package hint: nvidia-180-kernel-source

When trying to build the nVidia proprietary drivers against 2.6.31-rt
using DKMS, the build fails due to undefined reference to init_MUTEX.
The semaphore API seems to have been changed from 2.6.29 to remove the
init_MUTEX-macro. Applying patch from [1] allows the module to build. I
haven't yet tested if this actually works though.

Is there a way to report this bug also against the kernel image or
headers? This could probably be also fixed by restoring the init_MUTEX
macro as a custom patch in Ubuntu kernel. Perhaps patching the module is
cleaner though.
