Here is the Hurd side of the patch, completely untested.

There are two patches now which both works, Roland needs to decide which one to use (or if yet another interface is desired).

Beside the interface, the implementation is also quite incomplete. It only supports a single real memory object, without any range restrictions. Only permission restrictions are supported.

This is good enough to implement io_map properly and use tmpfs for shared memory objects. Other uses may require filling in the gaps.

In particular: Support for range restrictions, support for multiple objects, support for holes, support for creating proxies from proxies (in this case, all proxies should be resolved at proxy creation time!).
