Subject: [PATCH] Revert "x86/efi: Request desired alignment via the PE/COFF
headers"
This reverts commit:
aeffc4928ea2 ("x86/efi: Request desired alignment via the PE/COFF headers")
Linn reports that Signtool complains that kernels built with
CONFIG_EFI_STUB=y are violating the PE/COFF specification because
the 'SizeOfImage' field is not a multiple of 'SectionAlignment'.
This violation was introduced as an optimisation to skip having
the kernel relocate itself during boot and instead have the
firmware place it at a correctly aligned address.
No one else has complained and I'm not aware of any firmware
implementations that refuse to boot with commit aeffc4928ea2,
but it's a real bug, so revert the offending commit.

Subject: [PATCH 3/3] ARM: bcm2835: add rpi power domain driver
This patch adds support for several power domains on Raspberry Pi,
including USB (so it can be enabled even if the bootloader didn't do
it), and graphics.
This patch is the combined work of Eric Anholt (who wrote USB support
inside of the Raspberry Pi firmware driver, and wrote the non-USB
domain support) and Alexander Aring (who separated the original USB
work out from the firmware driver).

From 482626063d446eac1809e025a79ad0a7d45bc22d Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Wed, 16 Dec 2015 13:24:40 -0800
Subject: [PATCH 1/4] ARM: bcm2835: Split the DT for peripherals from the DT
for the CPU
The set of peripherals remained constant across bcm2835 (Raspberry Pi
1) and bcm2836 (Raspberry Pi 2), but the CPU was swapped out. Split
the files so that we can include just peripheral setup in 2836.

Subject: [PATCH 2/4] ARM: bcm2835: Move the CPU/peripheral include out of
common RPi DT.
For Raspberry Pi 2, we want to use the same general pin assignment
bits, but need to use bcm2836.dtsi for the CPU instead.

Subject: [PATCH 1/2] ARM: bcm2835: enable all bcm2835-relevant in defconfig
Rebuild bcm2835_defconfig using "make bcm2835_defconfig;
make savedefconfig", and enable manually the following features:
* all bcm2835-relevant drivers (MBOX, WDT, DMA, PWM, SND)
* enable regular stackprotector because CONFIG_CC_STACKPROTECTOR
disappear
* enable some new dependencies in order to keep LED heartbeat
( CONFIG_NEW_LEDS, CONFIG_LEDS_CLASS, CONFIG_LEDS_TRIGGERS )
The following options were removed, because they are enabled implicit:
CONFIG_RD_BZIP2, CONFIG_RD_LZMA, CONFIG_RD_XZ, CONFIG_RD_LZO,
CONFIG_USB_DWC2_HOST, CONFIG_EXT4_FS, CONFIG_EXT4_FS_POSIX_ACL
These options became obsolete:
CONFIG_RESOURCE_COUNTERS, CONFIG_SCSI_MULTI_LUN

From 48dbc164b40dd9195dea8cd966e394819e420b64 Mon Sep 17 00:00:00 2001
From: Paul Gortmaker <paul.gortmaker@windriver.com>
Date: Wed, 21 Oct 2015 14:04:47 +0100
Subject: [PATCH] certs: add .gitignore to stop git nagging about
x509_certificate_list
Currently we see this in "git status" if we build in the source dir:
Untracked files:
(use "git add <file>..." to include in what will be committed)
certs/x509_certificate_list
It looks like it used to live in kernel/ so we squash that .gitignore
entry at the same time. I didn't bother to dig through git history to
see when it moved, since it is just a minor annoyance at most.

+Etnaviv DRM master device
+=========================
+
+The Etnaviv DRM master device is a virtual device needed to list all
+Vivante GPU cores that comprise the GPU subsystem.
+
+Required properties:
+- compatible: Should be one of
+ "fsl,imx-gpu-subsystem"
+ "marvell,dove-gpu-subsystem"
+- cores: Should contain a list of phandles pointing to Vivante GPU devices
+
+example:
+
+gpu-subsystem {
+ compatible = "fsl,imx-gpu-subsystem";
+ cores = <&gpu_2d>, <&gpu_3d>;
+};
+
+
+Vivante GPU core devices
+========================
+
+Required properties:
+- compatible: Should be "vivante,gc"
+ A more specific compatible is not needed, as the cores contain chip
+ identification registers at fixed locations, which provide all the
+ necessary information to the driver.
+- reg: should be register base and length as documented in the
+ datasheet
+- interrupts: Should contain the cores interrupt line
+- clocks: should contain one clock for entry in clock-names
+ see Documentation/devicetree/bindings/clock/clock-bindings.txt
+- clock-names:
+ - "bus": AXI/register clock
+ - "core": GPU core clock
+ - "shader": Shader clock (only required if GPU has feature PIPE_3D)
+
+Optional properties:
+- power-domains: a power domain consumer specifier according to
+ Documentation/devicetree/bindings/power/power_domain.txt
+
+example:
+
+gpu_3d: gpu@00130000 {
+ compatible = "vivante,gc";
+ reg = <0x00130000 0x4000>;
+ interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,
+ <&clks IMX6QDL_CLK_GPU3D_CORE>,
+ <&clks IMX6QDL_CLK_GPU3D_SHADER>;
+ clock-names = "bus", "core", "shader";
+ power-domains = <&gpc 1>;
+};

Subject: [PATCH 1/9] drm: Create a driver hook for allocating GEM object
structs.
The CMA helpers had no way for a driver to extend the struct with its
own fields. Since the CMA helpers are mostly "Allocate a
drm_gem_cma_object, then fill in a few fields", it's hard to write as
pure helpers without passing in a driver callback for the allocate
step.

Subject: [PATCH 2/9] drm/vc4: Add a BO cache.
We need to allocate new BOs in the kernel as part of each frame, but
the CMA allocator is way too slow for that. As an optimization, keep
track of recently-freed BOs and reuse them, with a 1 second timeout to

This improves 3D performance by about 15%.

From d5bc60f6ad05b3c676b057bec662cfafc3ee24dd Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Sun, 18 Jan 2015 09:33:17 +1300
Subject: [PATCH 3/9] drm/vc4: Add create and map BO ioctls.
While there exist dumb APIs for creating and mapping BOs, one of the
rules is that drivers doing 3D acceleration have to provide their own
APIs for buffer allocation (besides, the pitch/height parameters of
the dumb alloc don't really make sense for a lot of 3D allocations).
v2: Use __u32-style types, use "drm.h" instead of <drm/drm.h>.

From b501bacc6060fd62654b756469cc3091eb53de3a Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Mon, 30 Nov 2015 12:34:01 -0800
Subject: [PATCH 8/9] drm/vc4: Add support for async pageflips.
An async pageflip stores the modeset to be done and executes it once
the BOs are ready to be displayed. This gets us about 3x performance
in full screen rendering with pageflipping.

From 214613656b5179f0daab6e0a080814b5100d45f0 Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Fri, 30 Oct 2015 10:09:02 -0700
Subject: [PATCH 9/9] drm/vc4: Add an interface for capturing the GPU state
after a hang.
This can be parsed with vc4-gpu-tools tools for trying to figure out
what was going on.
v2: Use __u32-style types.

From a0af2e538c80f3e47f1d6ddf120a153ad909e8ad Mon Sep 17 00:00:00 2001
From: Thomas Hellstrom <thellstrom@vmware.com>
Date: Wed, 2 Dec 2015 09:24:46 -0800
Subject: drm: Fix an unwanted master inheritance v2
A client calling drmSetMaster() using a file descriptor that was opened
when another client was master would inherit the latter client's master
object and all its authenticated clients.
This is unwanted behaviour, and when this happens, instead allocate a
brand new master object for the client calling drmSetMaster().
Fixes a BUG() throw in vmw_master_set().

Subject: netfilter: ipset: Fix extension alignment
The data extensions in ipset lacked the proper memory alignment and
thus could lead to kernel crash on several architectures. Therefore
the structures have been reorganized and alignment attributes added
where needed. The patch was tested on armv7h by Gerhard Wiesinger and
on x86_64, sparc64 by Jozsef Kadlecsik.

Incorrect index was used when the data blob was shrinked at expiration,
which could lead to falsely expired entries and memory leak when
the comment extension was used too.

Subject: [PATCH] realtek: rtlwifi: rtl8821ae: Fix lockups on boot
Date: Tue, 10 Nov 2015 10:46:11 -0600
In commit 54328e64047a5 ("rtlwifi: rtl8821ae: Fix system lockups on boot"),
an attempt was made to fix a regression introduced in commit 1277fa2ab2f9
("rtlwifi: Remove the clear interrupt routine from all drivers").
Unfortunately, there were logic errors in that patch that prevented
affected boxes from booting even after that patch was applied.
The actual cause of the original problem is unknown as none of the
developers have systems that are affected.

SCSI: Fix NULL pointer dereference in RTPM of block layer
The routines in scsi_pm.c assume that if a runtime-PM callback is
invoked for a SCSI device, it can only mean that the device's driver
has asked the block layer to handle the runtime power management (by
calling blk_pm_runtime_init(), which among other things sets q->dev).
However, this assumption turns out to be wrong for things like the ses
driver. Normally ses devices are not allowed to do runtime PM, but
userspace can override this setting. If this happens, the kernel gets
a NULL pointer dereference when blk_post_runtime_resume() tries to use
the uninitialized q->dev pointer.
This patch fixes the problem by checking q->dev in block layer before
handle runtime PM. Since ses doesn't define any PM callbacks and call
blk_pm_runtime_init(), the crash won't occur.
This fixes Bugzilla #101371.

Revert "SCSI: Fix NULL pointer dereference in runtime PM"
This reverts commit 49718f0fb8c9 ("SCSI: Fix NULL pointer dereference in
runtime PM")
The old commit may lead to a issue that blk_{pre|post}_runtime_suspend and
blk_{pre|post}_runtime_resume can not be called in pairs.
Take sr device as example, when sr device goes to runtime suspend,
blk_{pre|post}_runtime_suspend will be called since sr device defined
pm->runtime_suspend. But blk_{pre|post}_runtime_resume will not be called
since sr device doesn't have pm->runtime_resume. Then sr device can not
resume correctly anymore.

From: Paolo Bonzini <pbonzini@redhat.com>
Subject: [PATCH 2/3] KVM: svm: unconditionally intercept #DB
Date: Tue, 10 Nov 2015 13:22:53 +0100
This is needed to avoid the possibility that the guest triggers
an infinite stream of #DB exceptions (CVE-2015-8104).
VMX is not affected: because it does not save DR6 in the VMCS,
it already intercepts #DB unconditionally.
