Since the second kallsyms pass results in an increase of the kernel size, it may result in additional veneers to be emitted, potentially affecting the output of kallsyms itself if these symbols are visible to it, and for that reason, symbols whose names end in '_veneer' are ignored explicitly. However, when building Thumb2 kernels, such veneers are named differently if they also incur a mode switch, and since they are not filtered by kallsyms, they may cause the build to fail. So filter symbols whose names end in '_from_arm' or '_from_thumb' as well.
