I should clarify again: I am not suggesting that we drop 32-bit
support in the forseeable future.  (Well, I might eventually suggest
that we drop support for 32-bit *hardware* at some point, but not for
32-bit compat software.)  Linux's compat code is quite robust and is
even fairly maintainable.

I'm talking about x32, which is a different beast.
