If an md array with externally managed metadata (e.g. DDF or IMSM)
is in use, then we should not set safemode==2 at shutdown because:
1/ this is ineffective: user-space need to be involved in any 'safemode' handling,
2/ The safemode management code doesn't cope with safemode==2 on external metadata
and md_check_recover enters an infinite loop.
Even at shutdown, an infinite-looping process can be problematic, so this
could cause shutdown to hang.

wait_barrier() includes a counter, so we must call it precisely once
(unless balanced by allow_barrier()) for each request submitted.
Since
commit 20d0189b10
block: Introduce new bio_split()
in 3.14-rc1, we don't call it for the extra requests generated when
we need to split a bio.
When this happens the counter goes negative, any resync/recovery will
never start, and "mdadm --stop" will hang.

This set contains a change to the ABI for the hid-sensors drivers to bring them
in line with the long published documentation. Unfortunately, rather than
reporting true scale and offset values via sysfs they were reporting
some magic numbers that could only be converted to anything useful using
the HID sensors specification. I missed this entirely through the introduction
of a number of drivers, only picking up on it recently. Srinivas has had
user feedback about this as well. The patch set is too large to go as a fix
at this stage in the cycle and is not a regression fix as this was never
right and so will have to wait for the next merge window. Srinivas assures
me that there are relatively few pieces of hardware out there and he has
had a number of people contact him to point out that the drivers did not
obey the ABI. Hence hopefully the fallout of this, if any will be minor.
If we don't fix it now, it will only get worse going forward. There is no
sensible way of maintaining the incorrect ABI as it is simply returning
the wrong values through the standard interfaces.
Non IIO elements
* Introduce devm_kmemdup. Does what it says on the tin.
New drivers:
* hid-sensors rotation devices (output as quaternion)
* Freescale MPL115A2 presure and temperature sensor.
* Melexis mlx90614 contactless infrared sensor.
* Freescale MMA8452Q 3-axis accelerometer.
New functionality:
* Addition of multiple element callback to allow for sysfs interfaces to access
elements such as quaternions which have no useful meaning if all 4 elements
are not presented together. Other future usecases for this include
rotation matrices.
* Support for multiple element buffer entries for exactly the same uses as
the sysfs related elements described above.
* Quaternion support via the quaternion IIO modifier.
* TEMP_AMBIENT and TEMP_OBJECT modifiers to distinguish cases with thermopile
devices.
* hid-sensors gain sysfs access to the sensor readings. Previously these
drivers used the buffered interface only. This change involves some
additional hid-sensors core support to read poll values back from the devices
to allow the drivers to know roughly how long to wait for a result when
polling the sensor. There is also an associated hid-sensors abi to allow
the devices to be turned off between reads and powered up on demand.
Cleanups and fixes
* Hid sensors fix as described above. Result is to make the _scale and _offset
attributes applicable in the same way as for all other IIO drivers.
* Some additional documentation - mostly covering stuff that graduated from
staging without managing to take it's ABI docs with it.
* A series of little tidy ups to the exynos_adc driver that make the code
nicer to read and improve handling of some corner cases.
* A tidy up to mag3110 (logical fix rather than a real one ;). Also enable
user offset calibration for this device.
* Drop some left over IS_ERR() checks from ad799x that snuck through during
the cleanup in the last IIO patch set.
* Fix a naming issue from clashing patches in ak8975 - note the clash only
occured in the last IIO patch set, hence the fix needs to go through this
tree.
* A format string missmatch fix in ad7280.c. Unlikely to have ever had an
impact so not worth rushing through.

The Marvell Armada 38x platform has a SDHCI interface managed by the
sdhci-pxav3 MMC host driver. It therefore makes sense to enable this
driver in multi_v7_defconfig, which supports the Armada 38x platform.

Commit e461fcb ("xfs: remote attribute lookups require the value
length") passes the remote attribute length in the xfs_da_args
structure on lookup so that CRC calculations and validity checking
can be performed correctly by related code. This, unfortunately has
the side effect of changing the args->valuelen parameter in cases
where it shouldn't.
That is, when we replace a remote attribute, the incoming
replacement stores the value and length in args->value and
args->valuelen, but then the lookup which finds the existing remote
attribute overwrites args->valuelen with the length of the remote
attribute being replaced. Hence when we go to create the new
attribute, we create it of the size of the existing remote
attribute, not the size it is supposed to be. When the new attribute
is much smaller than the old attribute, this results in a
transaction overrun and an ASSERT() failure on a debug kernel:
XFS: Assertion failed: tp->t_blk_res_used <= tp->t_blk_res, file: fs/xfs/xfs_trans.c, line: 331
Fix this by keeping the remote attribute value length separate to
the attribute value length in the xfs_da_args structure. The enables
us to pass the length of the remote attribute to be removed without
overwriting the new attribute's length.
Also, ensure that when we save remote block contexts for a later
rename we zero the original state variables so that we don't confuse
the state of the attribute to be removes with the state of the new
attribute that we just added. [Spotted by Brain Foster.]

The current tmpfile handler does not initialize default ACLs. Doing so
within xfs_vn_tmpfile() makes it roughly equivalent to xfs_vn_mknod(),
which is already used as a common create handler.
xfs_vn_mknod() does not currently have a mechanism to determine whether
to link the file into the namespace. Therefore, further abstract
xfs_vn_mknod() into a new xfs_generic_create() handler with a tmpfile
parameter. This new handler calls xfs_create_tmpfile() and d_tmpfile()
on the dentry when called via ->tmpfile().

Under "heavy" RX load, the driver cannot handle the descriptors fast
enough. In detail, when a descriptor is consumed, its used flag is
cleared and once the RX budget is consumed all descriptors with a
cleared used flag are prepared to receive more data. Under load though,
the HW may constantly receive more data and use those descriptors with a
cleared used flag before they are actually prepared for next usage.
The head and tail pointers into the RX-ring should always be valid and
we can omit clearing and checking of the used flag.
