    Revert "linux: arc: disable kernel unwinding to fix modules loading"
    
    This reverts commit acd41539d630688e9891003c9b51cace3e113316.
    
    There's a fix in upstream that will at some point land in 4.4 stable as
    well so we'll get rid of this hack and with the next commit will apply
    upstream fix.
