I have no idea whether what I did was correct, but at least it is no less 
incorrect than the code currently
in there, which coredumps now for some reason (I wonder why it never crashed 
before). The test-bit macro
expects a bit-number, and not a mask which it is given in the current code.

So while fixing this, I also used the normal cpu_data macro for the 
cpu_has_watch() macro, instead of
looking at CPU(0).
