Yes, I know that usually out-of-tree modules are on their own.
However, this one may require a rethink..

(Sorry for not catching this sooner, I hadn't tried to deal with the
affected module since this patch hit linux-next in next-20161128)

    taint/module: Clean up global and module taint flags handling

Contains this chunk:

+       char false;     /* character printed when not tainted */
+       bool module;    /* also show as a per-module taint flag */
+};

and hilarity ensues when an out-of-tree module has this:

# ifndef true
#  define true  (1)
# endif
# ifndef false
#  define false (0)
# endif

My proposed fix: change true/false to tainted/untainted.  If this
is agreeable, I'll code and submit the fix.
