It looks to be that it was removed already, somewhat behind schedule, in
commit 9470565579f29486f4ed0ffa50774268b64994b0 after an initial attempt
was made in commit 3abf024d2abb79614d8c4cb25a70d5596f77d0ad.  I don't know
if there is a procedure for bringing it back but I would guess it's a call
for the x86 maintainers. I imagine they will want to at least know;

1. Why do you need init_mm exported?
2. Is there an alternative approach to using init_mm?
3. Assuming yes, what are the downsides?
4. When do you think the module will be ready for posting?  i.e. is this
   really something destined for mainline or some perma-out-of-tree?
