Actually, the forthcoming kernel patch already has a per-process
mmap-base. So the only change required in the kernel would be to
recognize ILP32 binaries and set the mmap-base accordingly (so, yeah,
I lied when I said no changes would be required... ;-). (This doesn't
mean that I think ILP32 support is a good idea...)
