Changes for Linux 4.8.12 [2][3]:
> A few moments ago, Greg Kroah-Hartman announced the release of the
> twelfth maintenance update of the Linux 4.8 kernel series, as well as
> the availability of Linux kernel 4.4.36 LTS.
>
> Only five days have passed since the release of Linux kernel 4.8.11,
> which most GNU/Linux distributions that are using the latest and most
> advanced Linux 4.8 branch did not even receive, as is the case of Solus
> and openSUSE Tumbleweed, and Linux kernel 4.8.12 is already here, which
> means that OS maintainers need to re-compile the new version, tweak it
> for their supported architectures, and push it to the repos.
>
> However, according to the appended shortlog and the diff since Linux
> kernel 4.8.11, it looks like Linux kernel 4.8.12 changes a total of 52
> files, with 390 insertions and 204 deletions, which means that it's not
> a major update. There are mostly architecture improvements for PA-RISC,
> PowerPC (PPC), Tile, and x86, updated drivers, and a few networking
> changes.

> "I'm announcing the release of the 4.8.12 kernel. All users of the 4.8
> kernel series must upgrade," said Greg Kroah-Hartman. "The updated 4.8.y
> git tree can be found at:
> git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
> linux-4.8.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."

> "Users of the Linux 4.8 kernel series are urged to update"
>
> DAX, IOMMU, MMC, SCSI, Intel PowerClamp Thermal, and USB are among the
> updated drivers included in the Linux 4.8.12 kernel release. The
> array-bounds warning has been hidden for the NFS file system, and the
> networking stack was updated with a couple of wireless improvements. It
> looks like there's also an AppArmor change for improved security, a few
> KVM (Kernel-based Virtual Machine) changes, and a mm fix.

> If you're using a GNU/Linux distribution powered by a kernel from the
> Linux 4.8 series, you are urged to update to today's Linux kernel 4.8.12
> point release as soon as possible, or more precisely as soon as it lands
> in the stable repositories of your favorite operating system. OS vendors
> and power users can download the Linux 4.8.12 kernel source archive
> right now from kernel.org or via our website.
