But only if it's greater than 64 kB.  The reason is that the descriptor
has only 20 bits for the limit, and a flag to tell whether the high 12
bits are all zero or the low 12 bits all one.  (Maybe we should print
the limit so that this restriction is obvious, like "0010f---", instead
of "0010ffff".)
