Eric Dumazet says:
====================
net: better validate user provided tunnel names
This series changes dev_valid_name() to not attempt reading
a possibly too long user-provided device name, then use
this helper in five different tunnel providers.
====================

This change updates the mlx5 interface to create mkey
on the device.
The updates in the command mailbox include increasing the
access mode type field to 5 bits in order to support additional
types such as MLX5_MKC_ACCESS_MODE_MEMIC which represents device
memory access type and will be used when registering MR on allocated
device memory.
All the places that use the old access mode format are adjusted as
well.

This patch adds the mlx5_ib driver implementation for the device
memory allocation API.
It implements the ib_device callbacks for allocation and deallocation
operations as well as a new mmap command support which allows mapping
an allocated device memory to a VMA.
The change also adds reporting of device memory maximum size and
alignment parameters reported in device capabilities.
The allocation/deallocation operations are using new firmware
commands to allocate MEMIC memory on the device.

This patch adds querying of device memory capabilities by the mlx5_core
driver during initialization.
Device memory capabilities is a new capability type and structure
which contains the necessary data that is needed for future device
memory allocation.
The presence of this new capabilities struct is indicated in the
general capabilities struct which is queried first by the driver.
If the presence bit is set, the driver will also query the new
capabilities struct and save it in the device context.

- ASoC componentization: finally each individual driver was converted
to components framework, which is more future-proof for further
works. Most of conversations were systematic.

codecs, typically tablets and small PCs.
- Fixes / cleanups for Samsung Odroid systems

Adding new ioctl method for the MR object - REG_DM_MR.
This command can be used by users to register an allocated
device memory buffer as an MR and receive lkey and rkey
to be used within work requests.
It is added as a new method under the MR object and using a new
ib_device callback - reg_dm_mr.
The command creates a standard ib_mr object which represents the
registered memory.

A new uverbs object is defined of type idr to represent

The API requires provider driver to implement 2 new ib_device

the allocated memory on the device.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of depending on
it. This is merged with the same pattern for all the ISA drivers
and some other Kconfig cleanups related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of this SoC
from the ARM tree.
- Move the documentation over to driver-api to conform with the rest
of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we
want to get rid of.
- Managed to remove VLA allocation from two drivers pending more
fixes in this area for the next merge window.

rxe driver's add_gid() and del_gid() callbacks are doing simple
checks which are already done by the ib core before invoking these
callback routines.
Therefore, code is simplified to skip implementing add_gid() and
del_gid() callback functions.
They are only invoked by ib_core if they are implemented.

The pkey code added a CPU_FTR_PKEY bit, but did not add it to the
dt_cpu_ftrs feature set. Although capability is supported by all
processors in the base dt_cpu_ftrs set for 64s, it's a significant
and sufficiently well defined feature to make it optional. So add
it as a quirk for now, which can be versioned out then controlled
by the firmware (once dt_cpu_ftrs gains versioning support).

Presently the dt_cpu_ftrs restore_cpu will only add bits to the LPCR
for secondaries, but some bits must be removed (e.g., UPRT for HPT).
Not clearing these bits on secondaries causes checkstops when booting
with disable_radix.
restore_cpu can not just set LPCR, because it is also called by the
idle wakeup code which relies on opal_slw_set_reg to restore the value
of LPCR, at least on P8 which does not save LPCR to stack in the idle
code.
Fix this by including a mask of bits to clear from LPCR as well, which
is used by restore_cpu.
This is a little messy now, but it's a minimal fix that can be
backported. Longer term, the idle SPR save/restore code can be
reworked to completely avoid calls to restore_cpu, then restore_cpu
would be able to unconditionally set LPCR to match boot processor
environment.

As described in that commit:
When stop is executed with EC=ESL=0, it appears to execute like a
normal instruction (resuming from NIP when woken by interrupt). So
all the save/restore handling can be avoided completely.
This is true, except in the case of an NMI interrupt (sreset or
machine check) interrupting the instruction. In that case, the NMI
gets an "interrupt occurred while the processor was in power-saving
mode" indication. The power-save wakeup code uses that bit to decide
whether to restore some registers (e.g., LR). Because these are no
longer saved, this causes random register corruption.
It may be possible to restore this optimisation by detecting the case
of no register loss on the wakeup side, and avoid restoring in that
case, but that's not a minor fix because the wakeup code itself uses
some registers that would be live (e.g., LR).
