Do as Greg says [1][2]:

> All users of the 4.8 kernel series must upgrade.

Enable certain tracers asked for by Peter (see diff at the end).

Note, that the regression in the *bnx2* driver, requiring firmware to be
present in the initramfs should be fixed.

Changes for Linux 4.8.9 [3][4]:

> Lately, new kernel releases are pushed like crazy, but we don't
> complain, as they always try to improve support for our devices or
> introduce security and bug fixes.
>
> Just four days after the release of Linux kernel 4.8.8, Greg
> Kroah-Hartman announced on November 19 the availability of the ninth
> maintenance update in the stable series, which currently powers
> several rolling distributions, including the popular Arch Linux,
> Solus, and openSUSE Tumbleweed. Linux kernel 4.8.9 is a fairly normal
> point release that changes a total of 97 files, with 725 insertions
> and 399 deletions.

> ### Here's what was changed since Linux kernel 4.8.8 ###
>
> Looking at the appended shortlog and the diff since Linux kernel
> 4.8.8, we can notice that Linux kernel 4.8.9 comes with an updated
> networking stack that includes multiple improvements for the SunRPC
> remote procedure call protocol, along with some minor Netfilter,
> B.A.T.M.A.N. Advanced, and Ceph fixes, a workaround to the
> -Wmaybe-uninitialized warning for NFS v4.1 filesystems, and a few
> sound stack updates.
>
> Moreover, it looks like there are a few improvements to the s390, x86,
> and ARC architectures, and dozens of updated drivers, in particular
> for things like GPU (AMDGPU, AMD GPU Scheduler, Intel i915, and
> Radeon), general-purpose input/output (GPIO), iiO, IOMMU, MMC, NFC,
> NVM Express (NVMe), PINCTRL, PCI, RTC, SCSI, TTY, USB, Ethernet, and
> Watchdog. Download Linux kernel 4.8.9 source archive now from
> kernel.org.

Changes for Linux 4.8.10 [5][6]:

> You won't believe this, but new maintenance updates for the long-term
> supported Linux 4.4 kernel branch, as well as the Linux 4.8 kernel
> series, have been published today, November 21, 2016.
>
> The Linux kernel 4.8.10 and Linux kernel 4.4.34 LTS point releases
> come just two days after their previous maintenance updates, namely
> Linux kernel 4.8.9 and Linux kernel 4.4.33 LTS, so we can't imagine
> how busy OS vendors must be these days updating the kernels for their
> supported architectures. We decided to write a single story about both
> of these new kernel patches because they include pretty much the same
> changes.
>
> "I'm announcing the release of the 4.8.10 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:

> browser:
> http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary."
>
> ### Many SPARC64 improvements, updated Ethernet drivers ###
>
> While Linux kernel 4.8.10 changes a total of 61 files, with 1624
> insertions and 801 deletions, Linux kernel 4.4.34 LTS changes 57
> files, with 1499 insertions and 803 deletions, according to their
> appended shortlogs. The biggest part of the new patches are
> improvements to the SPARC64 hardware architecture, but there's also an
> updated networking stack with many IPv4 changes and a few IPv6, DCCP,
> and SCTP fixes.
>
> The Linux kernel 4.8.10 and Linux kernel 4.4.34 LTS also include a few
> updates to the Ethernet drivers, for STMicroelectronics, Broadcom and
> Mellanox devices. It's not much, but you still need to update your
> GNU/Linux distribution to these new versions. Power users and OS
> vendors can download the Linux kernel 4.8.10 and Linux kernel 4.4.34
> LTS source archives right now from kernel.org or through our website.
