free -m & physpages reports around 37MB of RAM used, while privvmpages shows ~190MB of RAM, I know kmemsize reports something but what is that in? Is that included in the privvmpages?

Here is my user_beancounters

Why is there such a difference between physpages and privvmpages?

Thanks in advance,
