ASoC: Updates for v4.7
The updates this time around are almost all driver code:
- Further slow progress on the topology code.
- Substantial updates and improvements for the da7219, es8328, fsl-ssi
Intel and rcar drivers.

btrfs's fiemap is supposed to return 0 on success and return < 0 on
error. however, ret becomes 1 after looking up the last file extent:
btrfs_lookup_file_extent ->
btrfs_search_slot(..., ins_len=0, cow=0)
and if the offset is beyond EOF, we'll get 'path' pointed to the place
of potentail insertion, and ret == 1.
This may confuse applications using ioctl(FIEL_IOC_FIEMAP).

While reading sys_chunk_array in superblock, btrfs creates a temporary
extent buffer. Since we don't use it after finishing reading
sys_chunk_array, we don't need to keep it in memory.

git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"This set of changes introduces an atomic API to the PWM subsystem.
This is influenced by the DRM atomic API that was introduced a while
back, though it is obviously a lot simpler. The fundamental idea
remains the same, though: drivers provide a single callback to
implement the atomic configuration of a PWM channel.
As a side-effect the PWM subsystem gains the ability for initial state
retrieval, so that the logical state mirrors that of the hardware.
Many use-cases don't care about this, but for others it is essential.
These new features require changes in all users, which these patches
take care of. The core is transitioned to use the atomic callback if
available and provides a fallback mechanism for other drivers.
Changes to transition users and drivers to the atomic API are
postponed to v4.8"

Since the patch "NFS: Allow multiple commit requests in flight per file"
we can run multiple simultaneous commits on the same inode. This
introduced a race over collecting pages to commit that made it possible
to call nfs_init_commit() with an empty list - which causes crashes like
the one below.
The fix is to catch this race and avoid calling nfs_init_commit and
initiate_commit when there is no work to do.
Here is the crash:

Pull header warning fix from Dave Airlie:
"Here is the C++ guards warning fix from Arnd"
[ Background: there are 'extern "C" { }' guards in include/uapi for the
GPU headers.
They should arguably be wrapped somehow, but as it is they caused
checkpatch to warn because it would trigger on the 'extern' and think
it's exporting a function or variable from the kernel to user space.
This just fixes checkpatch. Whether we wrap the C++ guards some way
in the future will be an independent issue. ]

This patch adds a kvm debugfs subdirectory for each VM, which is named
after its pid and file descriptor. The directories contain the same
kind of files that are already in the kvm debugfs directory, but the
data exported through them is now VM specific.
This makes the debugfs kvm data a convenient alternative to the
tracepoints which already have per VM data. The debugfs data is easy
to read and low overhead.

The function to update APICv on/off state (in particular, to deactivate
it when enabling Hyper-V SynIC) is incomplete: it doesn't adjust
APICv-related fields among secondary processor-based VM-execution
controls. As a result, Windows 2012 guests get stuck when SynIC-based
auto-EOI interrupt intersected with e.g. an IPI in the guest.
In addition, the MSR intercept bitmap isn't updated every time "virtualize
x2APIC mode" is toggled. This path can only be triggered by a malicious
guest, because Windows didn't use x2APIC but rather their own synthetic
APIC access MSRs; however a guest running in a SynIC-enabled VM could
switch to x2APIC and thus obtain direct access to host APIC MSRs
(CVE-2016-4440).
The patch fixes those omissions.

When porting the hdmi deep color detection code from
radeon-kms to amdgpu-kms apparently some kind of
copy and paste error happened, attaching an else
branch to the wrong if statement.
The result is that hdmi deep color mode is always
disabled, regardless of gpu and display capabilities and
user wishes, as the code mistakenly thinks that the display
doesn't provide the required max_tmds_clock limit and falls
back to 8 bpc.
This patch fixes deep color support, as tested on a
R9 380 Tonga Pro + suitable display, and should be
backported to all kernels with amdgpu-kms support.

Commit:
b5179ac70de8 ("sched/fair: Prepare to fix fairness problems on migration")
... introduced a bug: Mike Galbraith found that it introduced a
performance regression, while Paul E. McKenney reported lost
wakeups and bisected it to this commit.
The reason is that I mis-read ttwu_queue() such that I assumed any
wakeup that got a remote queue must have had the task migrated.
Since this is not so; we need to transfer this information between
queueing the wakeup and actually doing the wakeup. Use a new
task_struct::sched_flag for this, we already write to
sched_contributes_to_load in the wakeup path so this is a hot and
modified cacheline.

imx-drm probing fix
Commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading")
broke probing of the imx-drm driver in the non-modular case because the
unset dev->of_node during probing of imx-ipuv3-crtc would cause the
component matching to fail. This patch patch instead matches against
an of_node pointer stored in platform data, allowing dev->of_node to
be left unset for the platform probed imx-ipuv3-crtc devices.

With the change to sparse IRQs, the lpc32xx platform gets a warning about
conflicting macros:
In file included from arch/arm/mach-lpc32xx/irq.c:31:0:
arch/arm/mach-lpc32xx/include/mach/irqs.h:115:0: warning: "NR_IRQS" redefined
#define NR_IRQS 96
arch/arm/include/asm/irq.h:9:0: note: this is the location of the previous definition
#define NR_IRQS NR_IRQS_LEGACY
One such instance was in the old irq driver that is now removed by
the previous patch, but any other file including mach/irqs.h still
has the issue. Since none of them use this constant, we can just
remove the old definition.

There is an assumption that rdmacm is used only between nodes
in the same IB subnet, this why ARP resolution can be used to turn
IP to GID in rdmacm.
When dealing with IB communication between subnets this assumption
is no longer valid. ARP resolution will get us the next hop device
address and not the peer node's device address.
To solve this issue, we will check user space if it can provide the
GID of the peer node, and fail if not.
We add a sequence number to identify each request and fill in the GID
upon answer from userspace.

and would place in an attribute (LS_NLA_TYPE_IPV4 or LS_NLA_TYPE_IPV6)

The local service would answer with a message that has the attribute:

IB address resolution is declared as a module (ib_addr.ko) which loads
itself before IB core module (ib_core.ko).
It causes to the scenario where IB netlink which is initialized by IB
core can't be used by ib_addr.ko.
In order to solve it, we are converting ib_addr.ko to be part of
IB core module.
