Since there is no way to figure out (as we know) from user space if a given memory region is backed by a huge page or default one, we can allow the user to supply us this info on memory registration. For that we need to add version of ibv_reg_mr() with additional input parameter for page size (the same for ibv_dontfork_range() and ibv_dofork_range()).
