Hi Pavan,

Perhaps this patch took more time than it should, but according Jerin's
description the problem is SoC can't run 32bit applications.

Why do you still mention from the kernel driver dependency? It looks like
that dependency is not reason to not compile 32 bit app, am I missing
something?
