trivial conflict in net/socket.c and non-trivial one in crypto -

Conflicts:
drivers/net/ethernet/mellanox/mlx4/cmd.c
net/core/fib_rules.c
net/ipv4/fib_frontend.c
The fib_rules.c and fib_frontend.c conflicts were locking adjustments
in 'net' overlapping addition and removal of code in 'net-next'.
The mlx4 conflict was a bug fix in 'net' happening in the same
place a constant was being replaced with a more suitable macro.

====================
Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
* VHT support for TDLS and IBSS (conditional on drivers though)
* first TX performance improvements (the biggest will come later)
* many suspend/resume (race) fixes
* name_assign_type support from Tom Gundersen

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.
Similar functionality was introduced for the rtnetlink core in
commit 5517750f05 ("net: rtnetlink - make create_link take name_assign_type")

3rd set of IIO fixes for the 4.0 cycle.
* A double free occured on an error path in due to an event registration issue.
The fix is the minimal change rather than possibly reworking this area of
the core to give a more elegant solution (future work).
* A number of drivers were directly accessing indio_dev->buffer->scan_mask
to identify the currently enabled channel set. This may not be correct
if we have additional clients on the push interface. The correct option
is indio_dev->active_scan_mask. This is fixed.
* bmc150 had incorrectly specified sampling frequency (a datasheet confusion
as they are specified in terms of bandwith - e.g. half the sampling
frequency).
* hmc5843 wasn't setting it's name and hence the name attribute was
returning an empty string.
* inv_mpu6050 wasn't clearing the locally held timestamp buffer when the
hardware fifo was reset. Also an inconsistency existed in the interface
for the scale of the channels. Magic numbers were written but real ones
were used for the reads. Now uses real numbers (i.e. not array indexes)
for both.
* fix a missing dependency in the dummy driver. Previously shielded from
the autobuilders by an earlier build error.
Without this change file name for hmc5843 is empty in
/sys/bus/iio/devices/iio\:device*/name
With this change name is reported correctly:

byRFType is not set prior to registration of mac80211 causing
unpredictable operation after channel scans.
With byRFType unset all channels are enabled this causes tx power
to be set to values not present its eeprom.
Move setting of this variable to vt6655_probe.
byRFType must have a mask set. byRevId not used by driver and

Reading of analog input channels by the `INSN_READ` comedi instruction
is broken for all except channel 0. `pci171x_ai_insn_read()` calls
`pci171x_ai_read_sample()` with the wrong value for the third parameter.
It is supposed to be the current index in a channel list (which is
always of length 1 in this case, so the index should be 0), but instead
it is passing the actual channel number. `pci171x_ai_read_sample()`
checks the channel number encoded in the raw sample value read from the
hardware matches the channel number stored in the specified index of the
previously set up channel list and returns `-ENODATA` if it doesn't
match. Since the index should always be 0 in this case, the match will
fail unless the channel number is also 0. Fix it by passing 0 as the
channel index.
Note that when the bug first appeared, it was `pci171x_ai_dropout()`
that was called with the wrong parameter value. `pci171x_ai_dropout()`
got replaced with `pci171x_ai_read_sample()` in commit 7fd2dae250
("staging: comedi: adv_pci1710: introduce pci171x_ai_read_sample()").
Fixes: 16c7eb6047 ("staging: comedi: adv_pci1710: always enable PCI171x_PARANOIDCHECK code")

During the attach of this driver a couple commands are sent to the hardware
with usb_bulk_msg() to read the firmware version information. This information
is then dumped as dev_info() kernel messages. Thee messages are just added
noise and don't effect the operation of the driver.
For simplicity, remove the messages as well as the then unused functions
vmk80xx_read_eeprom() and vmk80xx_check_data_link().
This also fixes an issue reported by coverity about an out-of-bounds write
in vmk80xx_read_eeprom().

The "stalled" variable this function is used to detect if the DMA operation
is stalled while trying to disable DMA on a full comedi sample. The reset
of this variable should only occur when the remaining bytes of the DMA
transfer does not equal the remaining bytes from the last check.

First round of fixes for IIO in the 4.0 cycle. Note a followup
set dependent on patches in the recent merge windows will follow shortly.
* dht11 - fix a read off the end of an array, add some locking to prevent
the read function being interrupted and make sure gpio/irq lines
are not enabled for irqs during output.
* iadc - timeout should be in jiffies not msecs
* mpu6050 - avoid a null id from ACPI emumeration being dereferenced.
* mxs-lradc - fix up some interaction issues between the touchscreen driver
and iio driver. Mostly about making sure that the adc driver
only affects channels that are not being used for the
touchscreen.
* ad2s1200 - sign extension fix for a result of c type promotion.
* adis16400 - sign extension fix for a result of c type promotion.
* mcp3422 - scale table was transposed.
* ad5686 - use _optional regulator get to avoid a dummy reg being allocate
which would cause the driver to fail to initialize.
* gp2ap020a00f - select REGMAP_I2C
* si7020 - revert an incorrect cleanup up and then fix the issue that made
that cleanup seem like a good idea.

it expects non-negative dentry, and in such cases ll_prep_inode() doesn't
modify *inode - it only uses the value.
