There are several architectures (powerpc comes to mind) where 32-bit
userspace on 64-bit kernel is the norm because it offers performance
advantages due to the smaller pointer size if the process doesn' t need
the larger address space. This is the rationale behind the new x32 ABI
for x86-64 kernels.

You might also want to run legacy apps (which can't be recompiled) on
new hardware.
