linux: Add stable version 4.9.20

Changes for Linux 4.9.19 [1][2][3]:

> Immediately after releasing the Linux 4.10.7 kernel, Greg
> Kroah-Hartman announced today the availability of the nineteenth
> maintenance update to the long-term supported Linux 4.9 kernel series.
>
> Just like Linux kernel 4.10.7, the Linux kernel 4.9.19 LTS release
> comes, surprisingly, only three days after the release of the previous
> maintenance update, in this case, Linux kernel 4.9.18 LTS. According
> to the appended shortlog, this is also a major patch that changes a
> total 98 files, with 812 insertions and 403 deletions. As expected,
> most of the patch are updated drivers.
>
> "I'm announcing the release of the 4.9.19 kernel. All users of the 4.9
> kernel series must upgrade. The updated 4.9.y git tree can be found
> at:
> git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
> linux-4.9.y and can be browsed at the normal kernel.org git web
> browser:
> http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary,"
> said Greg Kroah-Hartman.
>
> ### Updated USB and networking drivers, various improvements ###
>
> Among the changes implemented in the Linux 4.9.19 LTS kernel, we can
> mention updated CLK, CPUFreq, crypto, DAX, GPU (AMDGPU, analogix), HV,
> hwtracing, iiO, input (joystick, mouse, tablet, touchscreen), IOMMU,
> MMC, Ethernet (amd-xgbe, Broadcom GENET, Mellanox mlx5), Wireless
> (Marvell mwifiex), USB, UWB, and Xen drivers, as well as improvements
> to the EXT4 and JBD2 filesystems.
>
> The networking and sound stacks have been improved as well, with
> various improvements for Ceph, IPv4, IPv6, Open vSwitch, nl80211,
> cthw20k1, and Realtek, and there are a few bugs fixed for the ARM,
> ARM64, and PowerPC (PPC) architectures as well. If you're using a
> GNU/Linux distribution powered by a kernel from the Linux 4.9 LTS
> series, you are urged to update to version 4.9.19 as soon as possible.
> Download Linux kernel 4.9.19 LTS from kernel.org or via our website.

Changes for Linux 4.9.20 [4][5].

There are some small driver and scheduler fixes. Most importantly, a
local privilege-escalation vulnerability is fixed [6].

> Update: It appears that the urgency for getting these stable kernels
> out comes from a fix for CVE-2017-7184, which is a local
> privilege-escalation vulnerability.
