When removing a VLAN ID on a L3 device, the driver currently attempts to
walk and unregister the VLAN device's IP addresses.
This can be safely removed - before qeth_l3_vlan_rx_kill_vid() even gets
called, we receive an inet[6]addr event for each IP on the device and
qeth_l3_handle_ip_event() unregisters the address accordingly.

To support the next patch in this series which has code that calls
octnet_get_link_stats from two different .c files, move that function (and
its dependency octnet_nic_stats_callback) to lio_core.c. Remove

While adding the DSA notifier, we will be sending DSA notifications with
info->master that is going to point to a particular net_device instance.
Our logic in bcm_sysport_map_queues() correctly disambiguates net_device
instances that are not covered by our own driver, but it will not make
sure that info->master points to a particular driver instance that we
are interested in. In a system where e.g: two or more SYSTEMPORT
instances are registered, this would lead in programming two or more
times the queue mapping, completely messing with the logic which does
the queue/port allocation and tracking.
Fix this by looking at the notifier_block pointer which is unique per
instance and allows us to go back to our driver private structure, and
in turn to the backing net_device instance.

"Here are some small driver core and firmware fixes for 4.17-rc3
There's a kobject WARN() removal to make syzkaller a lot happier about

i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which
returns ZERO_SIZE_PTR if i2c_msg.len is zero.
Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case
of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in
case of zero len.
Let's check the len against zero before dereferencing buf pointer.

====================
pull-request: bpf-next 2018-04-27
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add extensive BPF helper description into include/uapi/linux/bpf.h
and a new script bpf_helpers_doc.py which allows for generating a
man page out of it. Thus, every helper in BPF now comes with proper
function signature, detailed description and return code explanation,
from Quentin.
2) Migrate the BPF collect metadata tunnel tests from BPF samples over
to the BPF selftests and further extend them with v6 vxlan, geneve
and ipip tests, simplify the ipip tests, improve documentation and
convert to bpf_ntoh*() / bpf_hton*() api, from William.
3) Currently, helpers that expect ARG_PTR_TO_MAP_{KEY,VALUE} can only
access stack and packet memory. Extend this to allow such helpers
to also use map values, which enabled use cases where value from
a first lookup can be directly used as a key for a second lookup,
from Paul.
4) Add a new helper bpf_skb_get_xfrm_state() for tc BPF programs in
order to retrieve XFRM state information containing SPI, peer
address and reqid values, from Eyal.
5) Various optimizations in nfp driver's BPF JIT in order to turn ADD
and SUB instructions with negative immediate into the opposite
operation with a positive immediate such that nfp can better fit
small immediates into instructions. Savings in instruction count
up to 4% have been observed, from Jakub.
6) Add the BPF prog's gpl_compatible flag to struct bpf_prog_info
and add support for dumping this through bpftool, from Jiri.
7) Move the BPF sockmap samples over into BPF selftests instead since
sockmap was rather a series of tests than sample anyway and this way
this can be run from automated bots, from John.
8) Follow-up fix for bpf_adjust_tail() helper in order to make it work
with generic XDP, from Nikita.
9) Some follow-up cleanups to BTF, namely, removing unused defines from
BTF uapi header and renaming 'name' struct btf_* members into name_off
to make it more clear they are offsets into string section, from Martin.
10) Remove test_sock_addr from TEST_GEN_PROGS in BPF selftests since
not run directly but invoked from test_sock_addr.sh, from Yonghong.
11) Remove redundant ret assignment in sample BPF loader, from Wang.
12) Add couple of missing files to BPF selftest's gitignore, from Anders.
There are two trivial merge conflicts while pulling:
1) Remove samples/sockmap/Makefile since all sockmap tests have been
moved to selftests.
2) Add both hunks from tools/testing/selftests/bpf/.gitignore to the
file since git should ignore all of them.

When deleting a flow counter, the modify mask should be the action and
the flow counter. Otherwise the flow counter is not deleted and we'll
get a firmware warning when deleting the remaining destinations on the
same FTE.
It only happens in the presence of flow counter and multiple vport
destinations. If there is only one vport destination, there is no
need to update the FTE when deleting the only vport destination,
we just delete the FTE.

When we fail to initialize the RX root namespace, we need

Currently the code may try to clean the flow steering twice
on error witch leads to null pointer deference.

Adding the vector offset when calling to mlx5_vector2eqn() is wrong.
This is because mlx5_vector2eqn() checks if EQ index is equal to vector number
and the fact that the internal completion vectors that mlx5 allocates
don't get an EQ index.
The second problem here is that using effective_affinity_mask gives the same
CPU for different vectors.
This leads to unmapped queues when calling it from blk_mq_rdma_map_queues().
This doesn't happen when using affinity_hint mask.

When the trust state is set to dscp and the netdev is down, the inline
header size is not updated. When netdev is up, the inline header size
stays at L2 instead of IP.
Fix this issue by updating the private parameter when the netdev is in

Pull ACPI fixes from Rafael Wysocki:
"These are two watchdog-related fixes, fix for a backlight regression
from the 4.16 cycle that unfortunately was propagated to -stable and a
button module modification to prevent graphics driver modules from
failing to load due to unmet dependencies if ACPI is disabled from the
kernel command line.
Specifics:
- Change the ACPI subsystem initialization ordering to initialize the
WDAT watchodg before reserving PNP motherboard resources so as to
allow the watchdog to allocate its resources before the PNP code
gets to them and prevents it from working correctly (Mika
Westerberg).
- Add a quirk for Lenovo Z50-70 to use the iTCO watchdog instead of
the WDAT one which conflicts with the RTC on that platform (Mika
Westerberg).
- Avoid breaking backlight handling on Dell XPS 13 2013 model by
allowing laptops to use the ACPI backlight by default even if they
are Windows 8-ready in principle (Hans de Goede)"

The block responsible of parsing the DT for the number of chip-select
lines uses an 'if/else if/else if' block. The content of the second and
third 'else if' conditions are:
1/ the actual condition to enter the sub-block and
2/ the operation to do in this sub-block.
[...]
else if (condition1_to_enter && action1() == failed)
raise_error();
else if (condition2_to_enter && action2() == failed)
raise_error();
[...]
In case of failure, the sub-block is entered and an error raised.
Otherwise, in case of success, the code would continue erroneously in
the next 'else if' statement because it did not failed (and did not
enter the first 'else if' sub-block).
The first 'else if' refers to legacy bindings while the second 'else if'
refers to new bindings. The second 'else if', which is entered
erroneously, checks for the 'reg' property, which, for old bindings,
does not mean anything because it would not be the number of CS
available, but the regular register map of almost any DT node. This
being said, the content of the 'reg' property being the register map
offset and length, it has '2' values, so the number of CS in this
situation is assumed to be '2'.
When running nand_scan_ident() with 2 CS, the core will check for an
array of chips. It will first issue a RESET and then a READ_ID. Of
course this will trigger two timeouts because there is no chip in front
of the second CS:
[ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080)
[ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280)
Indeed, this is harmless and the core will then assume there is only one
valid CS.
Fix the logic in the whole block by entering each sub-block just on the
'is legacy' condition, doing the action inside the sub-block. This way,
when the action succeeds, the whole block is left.
Furthermore, for both the old bindings and the new bindings the same
logic was applied to retrieve the number of CS lines:
using of_get_property() to get a size in bytes, converted in the actual
number of lines by dividing it per sizeof(u32) (4 bytes).
This is fine for the 'reg' property which is a list of the CS IDs but
not for the 'num-cs' property which is directly the value of the number
of CS.
Anyway, no existing DT uses another value than 'num-cs = <1>' and no
other value has ever been supported by the old driver (pxa3xx_nand.c).
Remove this condition and apply a number of 1 CS anyway, as already
described in the bindings.
Finally, the 'reg' property of a 'nand' node (with the new bindings)
gives the IDs of each CS line in use. marvell_nand.c driver first look
at the number of CS lines that are present in this property.
Better use of_property_count_elems_of_size() than dividing by 4 the size
of the number of bytes returned by of_get_property().

For ACPI support of the HiSilicon LPC driver we depend
on MFD_CORE config.
Currently the HiSi LPC Kconfig entry does not define this
dependency, so add it.
The reason for depending on MFD_CORE in the driver is
that we model the LPC host as an MFD, in that a platform
device will be created for each device on the bus.
We do this as we need to modify the resources of these
derived platform devices, something which we should not
do to the original devices created in the ACPI scan.
Details in e0aa1563f894 ("HISI LPC: Add ACPI support").
