Ftrace was one of the last W^X violators (and KLP it seems). These here patches move it over to the generic text_poke() interface and thereby get rid of this oddity.
The first 6 or so patches are more or less the same as in v3, except it has the bugs fixed that Steve found: - boot time function tracing works - module loading with function tracing works Then there's 10 new patches, that go all over the place, mostly inspired by staring at code touched by the first 6. That is, there's further ftrace and kprobes cleanups, as well fixes for various issues. In the end, it will have removed the horrible set_all_modules_text_*() interface and reduced the ftrace module loading to a single callback (again). The ARM patch is compiled only, I would be much obliged if someone could test that.
