kernel: update kernel 4.4 to version 4.4.19

Refresh patches for all targets that support kernel 4.4.
Compile-tested on all targets that use kernel 4.4 and aren't marked broken.
Runtime-tested on ar71xx, octeon and x86/64.

Subject: [PATCH v4] usb: dwc2: fix regression on big-endian PowerPC/ARM systems
Date: Fri, 13 May 2016 15:52:27 +0200
Message-Id: <1463147559-544140-1-git-send-email-arnd@arndb.de>
A patch that went into Linux-4.4 to fix big-endian mode on a Lantiq
MIPS system unfortunately broke big-endian operation on PowerPC
APM82181 as reported by Christian Lamparter, and likely other
systems.
It actually introduced multiple issues:
- it broke big-endian ARM kernels: any machine that was working
correctly with a little-endian kernel is no longer using byteswaps
on big-endian kernels, which clearly breaks them.
- On PowerPC the same thing must be true: if it was working before,
using big-endian kernels is now broken. Unlike ARM, 32-bit PowerPC
usually uses big-endian kernels, so they are likely all broken.
- The barrier for dwc2_writel is on the wrong side of the __raw_writel(),
so the MMIO no longer synchronizes with DMA operations.
- On architectures that require specific CPU instructions for MMIO
access, using the __raw_ variant may turn this into a pointer
dereference that does not have the same effect as the readl/writel.
This patch is a simple revert for all architectures other than MIPS,
in the hope that we can more easily backport it to fix the regression
on PowerPC and ARM systems without breaking the Lantiq system again.
We should follow this up with a more elaborate change to add runtime
detection of endianness, to make sure it also works on all other
combinations of architectures and implementations of the usb-dwc2
device. That patch however will be fairly large and not appropriate
for backports to stable kernels.
Felipe suggested a different approach, using an endianness switching
register to always put the device into LE mode, but unfortunately
the dwc2 hardware does not provide a generic way to do that. Also,
I see no practical way of addressing the problem more generally by
patching architecture specific code on MIPS.

Subject: [PATCH 317/423] videobuf2-v4l2: Verify planes array in buffer
dequeueing
commit 2c1f6951a8a82e6de0d82b1158b5e493fc6c54ab upstream.
When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer
which will be dequeued is not known until the buffer has been removed from
the queue. The number of planes is specific to a buffer, not to the queue.
This does lead to the situation where multi-plane buffers may be requested
and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument
struct with fewer planes.
__fill_v4l2_buffer() however uses the number of planes from the dequeued
videobuf2 buffer, overwriting kernel memory (the m.planes array allocated
in video_usercopy() in v4l2-ioctl.c) if the user provided fewer
planes than the dequeued buffer had. Oops!

Subject: [PATCH] ARC: unwind: ensure that .debug_frame is generated (vs.
.eh_frame)
With recent binutils update to support dwarf CFI pseudo-ops in gas, we
now get .eh_frame vs. .debug_frame. Although the call frame info is
exactly the same in both, the CIE differs, which the current kernel
unwinder can't cope with.
This broke both the kernel unwinder as well as loadable modules (latter
because of a new unhandled relo R_ARC_32_PCREL from .rela.eh_frame in
the module loader)
The ideal solution would be to switch unwinder to .eh_frame.
For now however we can make do by just ensureing .debug_frame is
generated by removing -fasynchronous-unwind-tables
.eh_frame generated with -gdwarf-2 -fasynchronous-unwind-tables
.debug_frame generated with -gdwarf-2

From 75ff39ccc1bd5d3c455b6822ab09e533c551f758 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <edumazet@google.com>
Date: Sun, 10 Jul 2016 10:04:02 +0200
Subject: [PATCH] tcp: make challenge acks less predictable
Yue Cao claims that current host rate limiting of challenge ACKS
(RFC 5961) could leak enough information to allow a patient attacker
to hijack TCP sessions. He will soon provide details in an academic
paper.
This patch increases the default limit from 100 to 1000, and adds
some randomization so that the attacker can no longer hijack
sessions without spending a considerable amount of probes.
Based on initial analysis and patch from Linus.
Note that we also have per socket rate limiting, so it is tempting
to remove the host limit in the future.
v2: randomize the count of challenge acks per second, not the period.
Fixes: 282f23c6ee34 ("tcp: implement RFC 5961 3.2")

On Cortex-A9 based Marvell SoCs, when HW I/O coherency is enabled, all
non-RAM space needs to be mapped strongly ordered.
In upstream this was added for PCIe I/O only, this change expands it
to cover all device memory. Fixes issues with CESA.
Based on patch from Thomas Petazzoni.
