If we have to support 32-bit applications on lk 2.4, what is the right way to do it? Any helpful suggestions are appreciated. >So you can only copy to the bottom 4GB of user address space?

That just makes people say "what the >**** are they doing?". May I also respectfully suggest that you don't use any F* or similar words in your mails, for the sole reason that our corporate server filters those mails out. We had to infer from Christoph's mail that you had responded earlier. We don't want to miss your valuable feedback.
