What I meant is: is the Vmalloc area really 32 *terra*bytes in size?
Seems rather big for a system with only 2GB RAM.

I'd never noticed it before and it looks strange to me, but I guess it's 
just the result of having 64-bit addressing: a theoretically addressable 
area most of which will never actually be used?
