Jukka Laitinen 7f8bec7070 Add mm/mm_map virtual memory mapping list 
The task_group specific list can be used to store information about
mmappings.

For a driver or filesystem performing mmap can also enable munmap by
adding an item to this list using mm_map_add(). The item is then
returned in the corresponding munmap call.
