Hi Willy-

Thanks very much for reviewing this.

I can hold out those lzo fixes until the next 3.13-stable if you prefer.
But fwiw...

I think those sorts of scheduling mismatches and discrepancies between
stable versions are pretty common.  Examples:  The top 11 commits in
v3.12.30 have not yet been applied[0] to any of the newer stable
branches;  Many of the commits in v3.10.57 have not yet been applied[1]
to linux-3.12.y but have been released in other newer stables.

We (the Canonical stable maintainers) have always tracked the "cc:
stable" fixes directly from mainline, not from the more-recent-version
branches.  Given the examples above, it seems that the kernel.org
maintainers are doing that too, yes?
