Pull module updates from Jessica Yu:
 "The most important change would be Christoph Hellwig's patch
  implementing proprietary taint inheritance, in an effort to discourage
  the creation of GPL "shim" modules that interface between GPL symbols
  and proprietary symbols.

  Summary:

   - Have modules that use symbols from proprietary modules inherit the
     TAINT_PROPRIETARY_MODULE taint, in an effort to prevent GPL shim
     modules that are used to circumvent _GPL exports. These are modules
     that claim to be GPL licensed while also using symbols from
     proprietary modules. Such modules will be rejected while non-GPL
     modules will inherit the proprietary taint.

   - Module export space cleanup. Unexport symbols that are unused
     outside of module.c or otherwise used in only built-in code"
