Did that. Under either kernel, the named process maps the same shared libraries, and the mappings are identical in size.
The difference is entirely in the process's private mappings, half of them are "rw-p" mappings, half of them are "---p" mappings, which I do not understand, a private mapping without read and write privileges?
The "rw-p" mappings are slightly larger under 4.7.2. The "---p" mappings are significantly larger under the 4.7.2 kernel.
