Android doesn't support LPAE? That's pretty surprising, any sources about that? LPAE doesn't need any usermode support to function. What specifically does Android do to prevent using LPAE in underlying Linux kernel?
Well, one thing is what Linux kernel supports by itself, other is, what does the board support package for your chipset. So maybe there is LPAE Android device somewhere, where the SoC provider did bother, but in general, nobody does.
