f2a3313d65 scsi: sd: Cleaned up comment references to @sdp argument explanation.
In sd.c there are two comment references to 'struct scsi_device *sdp' as
an argument.  One of the references has a typo and the other should be a
reference to 'struct device *dev' instead.

Fixed by correcting the typo in the first and changing the explanation
in the second.

cca112ecf2 spi: Fixes for v4.10
The usual small smattering of driver specific fixes.  A few bits that
 stand out here:
 
  - The R-Car patches adding fallbacks are just adding new compatible
    strings to the driver so that device trees are written in a more
    robustly future proof fashion, this isn't strictly a fix but it's
    just new IDs and it's better to get it into mainline sooner to
    improve the ABI.
  - The DesignWare "switch to new API part 2" patch is actually a
    misleadingly titled fix for a bit that got missed in the original
    conversion.

9a549c1e35 Merge branch 'dsa-hwmon'
Andrew Lunn says:

====================
net: dsa: Move temperature sensor code into PHY.

Marvell Ethernet switches contain a temperature sensor. There appears
to be one sensor, which is shared by each of the internal PHYs. Each
PHY has independent registers to read this sensor, and to set a limit
for when an alarm should be raised.

Some Marvell discrete PHY also have the same sensor and registers.
Moving the HWMON code from DSA into the PHY makes the sensor available
in discrete PHYs, and removes the layering violation, the switch
driver poking around in PHY registers.

While moving the code into the PHY driver, it has been re-written to
use the new HWMON APIs.

v2:

Better Cover note explaining one sensor, but multiple independent
registers

Simply error checking.
====================

cf1a56a4cf net: dsa: Remove hwmon support
Only the Marvell mv88e6xxx DSA driver made use of the HWMON support in
DSA. The temperature sensor registers are actually in the embedded
PHYs, and the PHY driver now supports it. So remove all HWMON support
from DSA and drivers.

7d982567f4 mlx5 and mlx5e updates 2017-01-19
This series includes some updates for mlx5 core and mlx5e netdevice driver.
 
 From Leon, a small fix that remove an unnecessary print.
 
 From Eli Cohen, a fix to the FW version printout in case of internal error.
 
 From Eugenia Emantayev, two patches, the 1st adds mlx5 1pps (pulse per
 second) mlx5 infrastructure support and the 2nd adds the necessary bits
 for mlx5e ptp logic and structures.
 
 From Mohamad, add support for s-tagged packet receive when in promiscuous
 mode.
 
 Form Gal Pressman, MCAM (Management capabilities mask register) and PCAM
 (Ports capabilities mask register) registers infrastructure, those
 registers are needed in order to query the different statistics registers
 support in FW, in order for the driver to enable/disable query and
 reporting them back to user.  On top of this infrastructure we've exposed
 new set of statistics groups:
    - MPCNT: Physical layer statistical counters (For symbol errors)
    - PPCNT: PCIe performance counters
 
 In addition to the statistics capabilities series we've moved the mlx5 HCA
 capabilities fields to a dedicated struct under the driver private data.
 
 At the end a small patch to update & query statistics in the most desired
 order.
 
 Thanks,
 Saeed.

90c311b0ee xen-netfront: Fix Rx stall during network stress and OOM
During an OOM scenario, request slots could not be created as skb
allocation fails. So the netback cannot pass in packets and netfront
wrongly assumes that there is no more work to be done and it disables
polling. This causes Rx to stall.

The issue is with the retry logic which schedules the timer if the
created slots are less than NET_RX_SLOTS_MIN. The count of new request
slots to be pushed are calculated as a difference between new req_prod
and rsp_cons which could be more than the actual slots, if there are
unconsumed responses.

The fix is to calculate the count of newly created slots as the
difference between new req_prod and old req_prod.

OMAP3621, DM3725, OMAP3615/DM3715, OMAP3611, and AM3703 all based on
features similar to what was done for the OMAP34xx/35xx series

The checkpatch flags some warnings for braces, but I kept the coding style
to match the adjacent code for consistency.

AM3703.

bd5e444bf1 ARM: OMAP5: Add HWMOD_SWSUP_SIDLE_ACT flag for UART
According to the commit ca43ea345d ("ARM: OMAP2+: hwmod: Add a new
flag to handle SIDLE in SWSUP only in active"), UART IP needs the sidle
mode to be controlled in SW only while they are active. Once inactive,
the IP needs to be put back in HW control so they are also wakeup
capable. The flag HWMOD_SWSUP_SIDLE takes care of this. So add this flag
to all instances of UART.

With this change, 8250 UART now gives out proper RX Timeout interrupts
and is usable as console.

e048fc50d7 net/mlx5e: Do not recycle pages from emergency reserve
A driver using dev_alloc_page() must not reuse a page allocated from
emergency memory reserve.

Otherwise all packets using this page will be immediately dropped,
unless for very specific sockets having SOCK_MEMALLOC bit set.

This issue might be hard to debug, because only a fraction of received
packets would be dropped.

====================
use netdev_is_rx_handler_busy() in few known cases

netdev_rx_handler_register() was recently split into two parts - (a) check
if the handler is used, (b) register the new handler, parts. This is
helpful in scenarios like bonding where at the time of registration there
is too much state to unwind and it should check if the device is free
before building that state. IPvlan and macvlan drivers don't have this
issue however it can make use of the same check instead of using a device
specific check.
