use d_alloc_parallel() for sillyunlink/lookup exclusion and
explicit rwsem (nfs_rmdir() being a writer and nfs_call_unlink() -
a reader) for rmdir/sillyunlink one.
That ought to make lookup/readdir/!O_CREAT atomic_open really

Merge "non urgent auxdata fix for v4.7 merge window" from Tony Lindgren:
Device tree auxdata handling fix that allows a match based on the
compatible string if no exact match based on the IO address is found.
This leaves out the need to patch auxdata for each driver when adding
new SoCs. And it also reprotedly fixes the issue of passing auxdata
to a child if the parent instantiates the child from DT as discussed
in the "[PATCH] of/platform: Allow secondary compatible match in
of_dev_lookup" mailing list thread.
As a minimal use case, let's also convert omap pinctrl auxdatato
use a generic match.
There is no need to get this in to the v4.6-rc cycle and it can wait
for v4.7 merge window. Note that these changes have now been sitting
in Linux next for about two weeks so far as I wanted to make sure no
new issues are popping up.

Merge "omap legacy boot vs dt boot fixes for v4.7 merge window"
from Tony Lindgren:
Legacy booting vs device tree booting fixes for omaps for
v4.7 merge window. These are not considered urgent fixes enough
for the v4.6-rc cycle, but we need them in v4.7 in order to drop
the last remaining board-*.c files for omap3 for v4.8 merge window.
On Nokia N900, we need to pass the MMC slot names for the legacy
user space to work. Let's do that using auxdata as the driver is
setting up things already with the pdata for legacy booting. Then
we can later on discuss if we may want to have some generic binding
describing where the MMC slots are on the device.
N900 also has had the ir-rx51 device driver unusable with multiarch
for a long time. Let's pass the dmtimer data in pdata for the driver
to get it going again. Then once things are working, we can eventually
change the driver to use just hrtimer and PWM framework. The driver
changes will be queued separately.

arm-ccn driver uses irq_set_affinity, which is not exported and
hence cannot be built as a module, eventhough we have all the
bits ready. This patch makes use of the exported helper
irq_set_affinity_hint() instead. Also, the __free_irq expects
the affinity_hint to be NULL when we free the irq. So set the
affinity_hint to NULL at clean up.
Now that we can build it as a module, update the Kconfig to
reflect the change.

The updated documentation regarding the IFI CANFD core from April 2016
adds more details regarding the timing calculation. There is no longer
any distinction in the timing calculation between CANFD and CAN2.0, but
instead there are two timing modes -- 4_12_6_6 and 7_9_8_8 -- where the
numbers mean the width in bits of the SJW/Prescaler/TimeA/TimeB fields.
The code uses 7_9_8_8 mode, which allows more fine-grained control over
the timing.
