talpa doesn't compile on ubuntu 17.04 linux 4.10

talpa doesn't compile since I upgraded to ubuntu 17.04.  This uses linux 4.10.

The last few lines of talpaselect.log are:

......

Traceback (most recent call last):

SelectException: exc-configure-failed-freeversion

I believe that the __lookup_mnt_last address function has been removed from linux 4.9 - see https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.15

I also raised this as an Issue on talpa in github at https://github.com/sophos/talpa/issues/2
