Fix a memory leak on probe error of the airspy usb device driver.
The problem is triggered when more than 64 usb devices register with
v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.
The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.
A badusb device can emulate 64 of these devices, and then through
continual emulated connect/disconnect of the 65th device, cause the
kernel to run out of RAM and crash the kernel, thus causing a local DOS
vulnerability.
Fixes CVE-2016-5400

In commit 2c1ea4c700af ("EDAC, sb_edac: Use cpu family/model in driver
detection") I broke Knights Landing because I failed to notice that it
called a wrapper macro "sbridge_get_all_devices_knl" instead of
"sbridge_get_all_devices" like all the other types.
Now that we include the processor type in the pci_id_table structure we
can skip the wrappers and just have the sbridge_get_all_devices() check
the type to decide whether to allow duplicate devices and controllers to
have registers spread across buses.

Some Kabylake SKUs are going to use Kabypoint PCH.
It is mainly for Halo and DT ones.
>From our specs it doesn't seem that KBP brings
any change on the display south engine. So let's consider
this as a continuation of SunrisePoint, i.e., SPT+.
Since it is easy to get confused by a letter change:
KBL = Kabylake - CPU/GPU codename.
KBP = Kabypoint - PCH codename.

Past evidence with system hangs and hsds tie
WaForceEnableNonCoherent and WaDisableHDCInvalidation to
WaForceContextSaveRestoreNonCoherent. Documentation
states that WaForceContextSaveRestoreNonCoherent would
not be needed on skl past E0 but evidence proved otherwise. See
commit <510650e8b2ab> ("drm/i915/skl: Fix spurious gpu hang with gt3/gt4

Currently, the q_vector initialization routine sets the affinity_mask
of a q_vector based on v_idx value. Meaning a loop iterates on v_idx,
which is an incremental value, and the cpumask is created based on
this value.
This is a problem in systems with multiple logical CPUs per core (like in
SMT scenarios). If we disable some logical CPUs, by turning SMT off for
example, we will end up with a sparse cpu_online_mask, i.e., only the first
CPU in a core is online, and incremental filling in q_vector cpumask might
lead to multiple offline CPUs being assigned to q_vectors.
Example: if we have a system with 8 cores each one containing 8 logical
CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is
disabled, only the 1st CPU in each core remains online, so the
cpu_online_mask in this case would have only 8 bits set, in a sparse way.
In general case, when SMT is off the cpu_online_mask has only C bits set:
0, 1*N, 2*N, ..., C*(N-1) where
C == # of cores;
N == # of logical CPUs per core.
In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set.
This patch changes the way q_vector's affinity_mask is created: it iterates
on v_idx, but consumes the CPU index from the cpu_online_mask instead of
just using the v_idx incremental value.
No functional changes were introduced.

Currently the function ixgbe_poll() returns 0 when it clean completely
the rx rings, but this foul budget accounting in core code.
Fix this returning the actual work done, capped to weight - 1, since
the core doesn't allow to return the full budget when the driver modifies
the napi status

There are a couple of issues I found in i40e_rx_checksum while doing some
recent testing. As a result I have found the Rx checksum logic is pretty
much broken and returning that the checksum is valid for tunnels in cases
where it is not.
First the inner types are not the correct values to use to test for if a
tunnel is present or not. In addition the inner protocol types are not a
bitmask as such performing an OR of the values doesn't make sense. I have
instead changed the code so that the inner protocol types are used to
determine if we report CHECKSUM_UNNECESSARY or not. For anything that does
not end in UDP, TCP, or SCTP it doesn't make much sense to report a
checksum offload since it won't contain a checksum anyway.
This leaves us with the need to set the csum_level based on some value.
For that purpose I am using the tunnel_type field. If the tunnel type is
GRENAT or greater then this means we have a GRE or UDP tunnel with an inner
header. In the case of GRE or UDP we will have a possible checksum present
so for this reason it should be safe to set the csum_level to 1 to indicate
that we are reporting the state of the inner header.

I've also realized that a pile of hang fixes for kbl landed in next, and
no one thought of backporting it to 4.7 - kbl has lost prelim_hw_support
tagging in 4.7-rc1 already. Mika is prepping a topic branch for those,
will send you a separate pull request since it's quite a bit (but should
be all well restricted to kbl code, so similar to polaris in amdgpu).

Commit e826eafa65c6 ("bonding: Call netif_carrier_off after
register_netdevice") moved netif_carrier_off() from bond_init() to
bond_create(), but the latter is called only for initial default
devices and ones created through sysfs:
$ modprobe bonding
$ echo +bond1 > /sys/class/net/bonding_masters
$ ip link add bond2 type bond
$ grep "MII Status" /proc/net/bonding/*
/proc/net/bonding/bond0:MII Status: down
/proc/net/bonding/bond1:MII Status: down
/proc/net/bonding/bond2:MII Status: up
Ensure that carrier is initially off also for devices created through
netlink.

Calling of_find_node_by_name() assumes that the caller has incremented
the refcount of the of_node being passed in. Currently, the caller is
not incrementing the refcount of the of_node which results in the node
being prematurely freed when of_find_node_by_name() calls of_node_put()
on it. Instead use of_get_child_by_name() which does not call put on the
of_node.

We can't sleep with RCU read lock held, but we need to do potentially
blocking stuff to namespace queues when iterating the list. This patch
removes the RCU locking and holds a mutex instead.
To prevent deadlocks, this patch removes holding the mutex during
namespace scanning and removal. The unlocked namespace scanning is made
safe by holding a reference to the namespace being scanned.
List iteration that does IO has to be unlocked to allow error recovery.
The caller must ensure the list can not be manipulated during such an
event, so this patch adds a comment explaining this requirement to the
only function that iterates an unlocked list. All callers currently
meet this requirement, so no further changes required.
List iterations that do not do IO can safely use the lock since it couldn't
block recovery from missing forced IO completions.

Dell XPS 13 9350 apparently doesn't like it when we use the panel type
from OpRegion. The OpRegion panel type (0) tells us to use use low
vswing for eDP, whereas the VBT panel type (2) tells us to use normal
vswing. The problem is that low vswing results in some display flickers.
Since no one seems to know how this stuff is supposed to be handled,
let's just ignore the OpRegion panel type on SKL for now.
