This patch removes the assumption made previously, that we only need to
check the delegation stateid when it matches the stateid on a cached
open.
If we believe that we hold a delegation for this file, then we must assume
that its stateid may have been revoked or expired too. If we don't test it
then our state recovery process may end up caching open/lock state in a
situation where it should not.
We therefore rename the function nfs41_clear_delegation_stateid as
nfs41_check_delegation_stateid, and change it to always run through the
delegation stateid test and recovery process as outlined in RFC5661.

NFSv4.0 does not have TEST_STATEID/FREE_STATEID functionality, so
unlike NFSv4.1, the recovery procedure when stateids have expired or
have been revoked requires us to just forget the delegation.

Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the
code in two drivers that matches time stamps with PTP frames, with the goal
of allowing VLAN tagged PTP packets to receive hardware time stamps.
However, that commit failed to account for the VLAN header when parsing
IPv4 packets. This patch fixes those two drivers to correctly match VLAN
tagged IPv4/UDP PTP messages with their time stamps.
This patch should also be applied to v3.17.

For pNFS direct writes, layout driver may dynamically allocate ds_cinfo.buckets.
So we need to take care to free them when freeing dreq.
Ideally this needs to be done inside layout driver where ds_cinfo.buckets
are allocated. But buckets are attached to dreq and reused across LD IO iterations.
So I feel it's OK to free them in the generic layer.

In commit a1253ef6d3fa ("ASoC: cs42l51: split i2c from codec driver"),
the I2C part of the CS42L51 was moved to a separate file, but the
definition of the of_device_id array was left in the driver file
itself, no longer connected to the platform_driver structure using the
.of_match_table pointer.
This commit exports the of_device_id array in cs42l51, and uses it as
.of_match_able in cs42l51-i2c.c. This solution was suggested by Brian
Austin.

On certain SoCs such as AM437x SoC, L3_noc error registers are
maintained in power domain such as per domain which looses context as part
of low power state such as RTC+DDR mode. On these platforms when we
mask interrupts which we cannot handle, the source of these interrupts
still remain on resume, however, the flag mux registers now contain
their reset value (unmasked) - this breaks the system with infinite
interrupts since we do not these interrupts to take place ever again.
To handle this: restore the masking of interrupts which we have
already recorded in the system as ones we cannot handle.

BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHz A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x1080@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.
For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15
AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page
Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6
Just add basic support for the moment, the following updates are needed:
i) Ethernet - depends on SoC dts fixes
ii) USB Client (USB2) - depends on GPIO extcon
ii) HDMI - additional driver fixes pending
iii) Audio - additional driver fixes pending
NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

On the LeMaker Banana Pi, probing the external ethernet PHY connected
to the SoC's internal GMAC module sometimes fails. The PHY power
supply is handled via a GPIO-controlled regulator, and the existing
regulator startup-delay of 50000us is too short to make sure that the
PHY is always fully powered up when it is queried by phylib. Tests
have shown that to provide a reliable PHY detection, the startup-delay
has to be increased to at least 60000us. To have a certain safety margin
and to cater for manufacturing variations between different boards,
the delay gets set to 100000us as discussed on the linux-arm-kernel
mailinglist.

The existing xtables matches and targets, when used from nft_compat, may
sleep from the destroy path, ie. when removing rules. Since the objects
are released via call_rcu from softirq context, this results in lockdep
splats and possible lockups that may be hard to reproduce.
Patrick also indicated that delayed object release via call_rcu can
cause us problems in the ordering of event notifications when anonymous
sets are in place.
So, this patch restores the synchronous object release from the commit
and abort paths. This includes a call to synchronize_rcu() to make sure
that no packets are walking on the objects that are going to be
released. This is slowier though, but it's simple and it resolves the
aforementioned problems.
This is a partial revert of c7c32e7 ("netfilter: nf_tables: defer all
object release via rcu") that was introduced in 3.16 to speed up
interaction with userspace.

Check for nat chain dependency only, which is the one that can
actually crash the kernel. Don't care if mangle, filter and security
specific match and targets are used out of their scope, they are
harmless.
This restores iptables-compat with mangle specific match/target when
used out of the OUTPUT chain, that are actually emulated through filter
chains, which broke when performing strict validation.
