32 bit and different arches are handled by config changes not by code
change.  I don't know much about Arm, have you ported much code to the
arch? I would assume it is not trivial work to get Lustre on 32 bit Arm
but likely newer Lustre will be easier than older Lustre.

You may want to look at the Linux Kernel staging tree and see if you can
get the Lustre Client working in your environment.  You will likely
learn alot about the process and the challenges if you can accomplish
this.  

Thanks,
