Is the reason for the modulo to put a bitmask larger then the variable 
into an array?
    

The complementary LONG() macro will tell you the index of an array of
longs where the bit should be set.
  

This may be a little OT, but how come it is not done as an function? 
Maybe something like "(set/get)_long_mask(...)".

We have it. Is is called set_bit (or __set_bit) and works wery well for
single bit operations, but sometimes it is nice to be able to write

	a = BIT(b) | BIT(c);
