The signature for a function that returns int and has no args is "i:".
It's academic though.  Functions without pointers in their signature
need no BP thunks, so their signatures are unnecessary.  Even so, I
write signatures for them anyway for sake of completeness.

I verified that no arg counts changed, and that none of your
signatures is inconsistent with those for other architectures.

The user-level API for mmap has a pointer as the first argument,
so you should have a signature for mmap.
