Changes from v1 -> v2: - Substantially rewrote "fix feature support detection"; previously, it tried to do some larger refactor wherein the global test_uffdio_* variables were removed. This was controversial, so it now simply queries features in set_test_type, and leaves the rest of the program structure largely the same. - The "fix calculation of expected ioctls" patch is conceptually the same as v1, but changed slightly to fit with the modified feature support detection in v2. - Moved patch 3/3 to 1/3, since it is uncontroversial and could be merged on its own. I don't want the other two to cause merge conflicts for it in future versions. - Picked up a R-B.
