Wait, this patch breaks the build for 4.4.y and 4.9.y, so this isn't
going to work well:

lib/interval_tree_test.c: In function ‘interval_tree_test_init’:
lib/interval_tree_test.c:105:38: error: ‘max_endpoint’ undeclared (first use in this function); did you mean ‘tracepoint’?
    unsigned long last = search_all ? max_endpoint : queries[j];
                                      ^~~~~~~~~~~~
                                      tracepoint


So I'm going to drop these from the 4.4 and 4.9 and 3.18 trees.  How did they
build for you?

confused,
