Subject: [PATCH] Revert "include/uapi/linux/atm_zatm.h: include linux/time.h"
This reverts commit cf00713a655d3019be7faa184402f16c43a0fed3.
It causes linux-atm build breakage between glibc headers and kernel headers...
Fixws are in progress upstream as of:
https://patchwork.kernel.org/patch/9294305/
But it's not accepted yet so it might still change, and since its uapi
we dont want to expose changes that might never land upstream.

Subject: [PATCH] ARM: bcm2835: dt: Add the ethernet to the device trees
The hub and the ethernet in its port 1 are hardwired on the board.
Compared to the adapters that can be plugged into the USB ports, this
one has no serial EEPROM to store its MAC. Nevertheless, the Raspberry Pi
has the MAC address for this adapter in its ROM, accessible from its
firmware.
U-Boot can read out the address and set the local-mac-address property of the
node with "ethernet" alias. Let's add the node so that U-Boot can do its
business.
Model B rev2 and Model B+ entries were verified by me, the hierarchy and
pid/vid pair for the Version 2 was provided by Peter Chen. Original
Model B is a blind shot, though very likely correct.

From 5c33677c87cbe44ae04df69c4a29c1750a9ec4e5 Mon Sep 17 00:00:00 2001

Date: Tue, 11 Oct 2016 15:16:57 +0100
Subject: [PATCH] dm raid: fix compat_features validation
In ecbfb9f118bce4 ("dm raid: add raid level takeover support") a new
compatible feature flag was added. Validation for these compat_features
was added but this only passes for new raid mappings with this feature
flag. This causes previously created raid mappings to be failed at
import.
Check compat_features for the only valid combination.
Fixes: ecbfb9f118bce4 ("dm raid: add raid level takeover support")

From 5a920b85f2c6e3fd7d9dd9bb3f3345e9085e2360 Mon Sep 17 00:00:00 2001

Date: Tue, 4 Oct 2016 14:37:32 -0300
Subject: drm/i915/gen9: fix DDB partitioning for multi-screen cases
With the previous code we were only recomputing the DDB partitioning
for the CRTCs included in the atomic commit, so any other active CRTCs
would end up having their DDB registers zeroed. In this patch we make
sure that the computed state starts as a copy of the current
partitioning, and then we only zero the DDBs that we're actually
going to recompute.
How to reproduce the bug:
1 - Enable the primary plane on pipe A
2 - Enable the primary plane on pipe B
3 - Enable the cursor or sprite plane on pipe A
Step 3 will zero the DDB partitioning for pipe B since it's not
included in the commit that enabled the cursor or sprite for pipe A.
I expect this to fix many FIFO underrun problems on gen9+.
v2:
- Mention the cursor on the steps to reproduce the problem (Paulo).
- Add Testcase tag provided by Maarten (Maarten).
Testcase: kms_cursor_legacy.cursorA-vs-flipB-atomic-transitions

Subject: [PATCH] intel_th: Fix a deadlock in modprobing
Driver initialization tries to request a hub (GTH) driver module from
its probe callback, resulting in a deadlock.
This patch solves the problem by adding a deferred work for requesting
the hub module.

Subject: [PATCH] cpupower: Correct return type of cpu_power_is_cpu_online in

To: Thomas Renninger <trenn@suse.com>
Cc: linux-pm@vger.kernel.org
Cc: linux-kernel@vger.kernel.org
When converting to a shared library in ac5a181d065d ("cpupower: Add
cpuidle parts into library"), cpu_freq_cpu_exists was converted to
cpupower_is_cpu_online. cpu_req_cpu_exists returned 0 on success and
-ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success.
Check for the correct return value in cpufreq-set.
See https://bugzilla.redhat.com/show_bug.cgi?id=1374212
Fixes: ac5a181d065d ("cpupower: Add cpuidle parts into library")

From fcd91dd449867c6bfe56a81cabba76b829fd05cd Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: add recursion limit to GRO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, GRO can do unlimited recursion through the gro_receive
handlers. This was fixed for tunneling protocols by limiting tunnel GRO
to one level with encap_mark, but both VLAN and TEB still have this
problem. Thus, the kernel is vulnerable to a stack overflow, if we
receive a packet composed entirely of VLAN headers.
This patch adds a recursion counter to the GRO layer to prevent stack
overflow. When a gro_receive function hits the recursion limit, GRO is
aborted for this skb and it is processed normally. This recursion
counter is put in the GRO CB, but could be turned into a percpu counter
if we run out of space in the CB.
Thanks to Vladimír Beneš <vbenes@redhat.com> for the initial bug report.
Fixes: CVE-2016-7039
Fixes: 9b174d88c257 ("net: Add Transparent Ethernet Bridging GRO support.")
Fixes: 66e5133f19e9 ("vlan: Add GRO support for non hardware accelerated vlan")

Subject: [PATCH] rtlwifi: Fix regression caused by commit d86e64768859
In commit d86e64768859 ("rtlwifi: rtl818x: constify local structures"),
the configuration struct for most of the drivers was changed to be
constant. The problem is that five of the modified drivers need to be
able to update the firmware name based on the exact model of the card.
As the file names were stored in one of the members of that struct,
these drivers would fail with a kernel BUG splat when they tried to
update the firmware name.
Rather than reverting the previous commit, I used a suggestion by
Johannes Berg and made the firmware file name pointers be local to
the routines that update the software variables.
The configuration struct of rtl8192cu, which was not touched in the
previous patch, is now constantfied.

From 1e90a13d0c3dc94512af1ccb2b6563e8297838fa Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Sat, 29 Oct 2016 13:42:42 +0200
Subject: [PATCH] x86/smpboot: Init apic mapping before usage
The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.
The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.
There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().
In hindsight, I should have noticed that combination earlier.
Sorry for the churn (also in stable)!
Fixes: ff8560512b8d ("x86/boot/smp: Don't try to poke disabled/non-existent APIC")
