linux: Add version 4.8-rc2

Announcement for Linux 4.8-rc1 [1]:

> It's been two weeks, and the merge window for 4.8 is thus closed.
>
> Due to travel last week, I actually still have a few pull requests
> pending in my inbox that I just wanted to take another look at before
> merging, but the large bulk of the merge window material has been
> merged, and I wanted to make sure there aren't any new ones coming in.
>
> This seems to be building up to be one of the bigger releases lately,
> but let's see how it all ends up. The merge window has been fairly
> normal, although the patch itself looks somewhat unusual: over 20% of
> the patch is documentation updates, due to conversion of the drm and
> media documentation from docbook to the Sphinx doc format. There are
> other doc updates, but that's the big bulk of it.
>
> If you ignore the documentation format change, things look fairly
> regular, with about 60% of the non-documentation diffs being drivers
> (gpu, networking, media, sound, etc)  and about 15% being arch updates
> (arm, powerpc and x86 dominate, but there's mips and s390 too).
>
> The rest is spread out - core networking, tooling (mainly perf),
> include files, core kernel, vfs and low-level filesystems (xfs stands
> out). Few areas escaped:
>
>   10787 files changed, 612208 insertions(+), 272098 deletions(-)
>
> Go out and test. The diffs and logs are too big to post, so as usual
> for rc1, I'm just appending my "merge log" for a very high-level view.
