Small clarification:

I was of course referring to the original patch for the issue:

  https://lkml.org/lkml/2014/9/9/498

stubs can be added properly with using 

  #if defined(CONFIG_COMPILE_TEST) && !defined(CONFIG_ARCH_OMAP1)

similarly like it is handled for ARCH_QCOM in

  drivers/gpu/drm/msm/msm_drv.h
