Hi Greg. This is for 4.4. This is a follow-up to "l2tp locking and ordering fixes" for 4.9. Compared with that series, this pulls in 5 more patches (the first 5 Guillaume Nault ones below) containing more of the same as well as making later changes apply more cleanly. As before, every commit compiles with make allmodconfig, but I have no hardware to test this with. 9dd79945b0f8 (use IS_ENABLED) would have made one patch or so cleaner but I didn't add it. There are also bunch of fixes that aren't l2tp locking or ordering fixes and I didn't add them either. For the record...
