For the patch,

Acked-by: Anatoly Burakov <anatoly.burakov@intel.com>

However i think it's incomplete, as there are also memory-backing 
fbarrays that are still mapped. Also, secondary processes have their own 
shadow copies of the master page table located in the mem config, so 
those should be destroyed on cleanup too.

Thanks,
Anatoly
