If of_node is set before calling platform_device_add, the driver core
will try to use of: modalias matching, which fails because the device
tree nodes don't have a compatible property set. This patch fixes
imx-ipuv3-crtc module autoloading by setting the of_node property only
after the platform modalias is set.

Regulators are optional for devices using OPPs and the OPP core
shouldn't be printing any errors for such missing regulators.
It was fine before the commit 0c717d0f9cb4, but that failed to update
this part of the code to remove an 'always true' check and an extra
unwanted print message.
Fix that now.

declare compat version in their syscall tables for preadv2 and
pwritev2. Generic unistd syscall table should do it as well.
[arnd: this initially slipped through the review and an
incorrect patch got merged. arch/tile/ is the only architecture
that could be affected for their 32-bit compat mode, every

10GbE Intel Wired LAN Driver Updates 2016-05-04
This series contains updates to ixgbe, ixgbevf and traffic class helpers.
Sridhar adds helper functions to the tc_mirred header to access tcf_mirred
information and then implements them for ixgbe to enable redirection to
a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action.
Amritha adds support to set filters with multiple header fields (L3,L4)
to match on.
KY Srinivasan from Microsoft add Hyper-V support into ixgbevf.
Emil adds 82599 sub-device IDs that were missing from the list of parts
that support WoL. Then simplified the logic we use to determine WoL
support by reading the EEPROM bits for MACs X540 and newer.
Preethi cleaned up duplicate and unused device IDs. Fixed our ethtool
stat reporting where we were ignoring higher 32 bits of stats registers,
so fill out 64 bit stat values into two 32 bit words.
Babu Moger from Oracle improves VF performance issues on SPARC.
Alex Duyck cleans up some of the Hyper-V implementation from KY so that
we can just use function pointers instead of having to identify if a
given VF is running on a Linux or Windows PF.
Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and
cleans up the DCB initialization in the process.
Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not
have to pass in the netdev parameter, since it was never used in the
function.

The code determines if the next ring entry is valid before proceeding
further to read the rest of the entry. The CPU can re-order and read
the rest of the entry first, possibly reading a stale entry, if DMA
of a new entry happens right after reading it. This issue can be
readily seen on a ppc64 system, causing it to crash.

tcp_snd_una_update() and tcp_rcv_nxt_update() call
u64_stats_update_begin() either from process context or BH handler.
This triggers a lockdep splat on 32bit & SMP builds.
We could add u64_stats_update_begin_bh() variant but this would
slow down 32bit builds with useless local_disable_bh() and
local_enable_bh() pairs, since we own the socket lock at this point.
I add sock_owned_by_me() helper to have proper lockdep support
even on 64bit builds, and new u64_stats_update_begin_raw()

1) The flowcache can hit an OOM condition if too
many entries are in the gc_list. Fix this by
counting the entries in the gc_list and refuse
new allocations if the value is too high.
2) The inner headers are invalid after a xfrm transformation,
so reset the skb encapsulation field to ensure nobody tries
access the inner headers. Otherwise tunnel devices stacked
on top of xfrm may build the outer headers based on wrong
informations.
3) Add pmtu handling to vti, we need it to report
pmtu informations for local generated packets.

net: remove trans_start from struct net_device
We currently have two instances for trans_start, once in
net_device and once in netdev_queue.
This series removes trans_start from net_device.
Updates to dev->trans_start are replaced with updates to netdev queue 0.
This series is compile-tested only.
Replacement is done in 3 steps:
1. Replace read-accesses:
x = dev->trans_start
gets replaced by
x = dev_trans_start(dev)
2. Replace write accesses:
dev->trans_start = jiffies;
gets replaced with new helper:
netif_trans_update(dev);
3. This helper is then changed to set
netdev_get_tx_queue(dev, 0)->trans_start
instead of dev->trans_start.
After this dev->trans_start can be removed.
It should be noted that after this series several instances
of netif_trans_update() are useless (if they occur in
.ndo_start_xmit and driver doesn't set LLTX flag -- stack already
did an update).
Comments welcome.

previous patches removed all direct accesses to dev->trans_start,
so change the netif_trans_update helper to update trans_start of
netdev queue 0 instead and then remove trans_start from struct net_device.
AFAICS a lot of the netif_trans_update() invocations are now useless
because they occur in ndo_start_xmit and driver doesn't set LLTX
(i.e. stack already took care of the update).
As I can't test any of them it seems better to just leave them alone.

trans_start exists twice:
- as member of net_device (legacy)
- as member of netdev_queue
In order to get rid of the legacy case, add a helper for the
dev->trans_update (this patch), then convert spots that do
dev->trans_start = jiffies
to use this helper (next patch).
This would then allow us to change the helper so that it updates the
trans_stamp of netdev queue 0 instead.

a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue
Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.
This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.
For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).
This is a prerequisite to eventual removal of dev->trans_start.

gre: receive also TEB packets for lwtunnels
NOTE: this patchset needs net merged to net-next.
This allows lwtunnel users to get also packets with ETH_P_TEB protocol
specified in GRE header through an ipgre interface. There's really nothing
special about these packets in the case of lwtunnels - it's just an inner
protocol like any other. The only complications stem from keeping
compatibility with other uses of GRE.
This will be used by openvswitch to support eth_push and eth_pop actions.
I'd also like to see tc support for lwtunnels (this feature included) in the
future.

For ipgre interfaces in collect metadata mode, receive also traffic with
encapsulated Ethernet headers. The lwtunnel users are supposed to sort this
out correctly. This allows to have mixed Ethernet + L3-only traffic on the
same lwtunnel interface. This is the same way as VXLAN-GPE behaves.
To keep backwards compatibility and prevent any surprises, gretap interfaces
have priority in receiving packets with Ethernet headers.

The call to gre_parse_header is either followed by iptunnel_pull_header, or
in the case of ICMP error path, the actual header is not accessed at all.
In the first case, iptunnel_pull_header will call pskb_may_pull anyway and
it's pointless to do it twice. The only difference is what call will fail
with what error code but the net effect is still the same in all call sites.
In the second case, pskb_may_pull is pointless, as skb->data is at the outer
IP header and not at the GRE header.

In the receive path a queue's work bit was cleared unconditionally even
if fec_enet_rx_queue only read out a part of the available packets from
the hardware. This resulted in not reading any packets in the next napi
turn and so packets were delayed or lost.
The obvious fix is to only clear a queue's bit when the queue was
emptied.

Mellanox 100G ethernet SRIOV Upgrades
This series introduces new features and upgrades for mlx5 etherenet SRIOV,
while the first patch provides a bug fixes for a compilation issue introduced
buy the previous aRFS series for when CONFIG_RFS_ACCEL=y and CONFIG_MLX5_CORE_EN=n.
Changes from V0:
- 1st patch: Don't add a new Kconfig flag. Instead, compile out en_arfs.c \
contents when CONFIG_RFS_ACCEL=n
SRIOV upgrades:
- Use synchronize_irq instead of the vport events spin_lock
- Fix memory leak in error flow
- Added full VST support
- Spoofcheck support
- Trusted VF promiscuous and allmulti support
VST and Spoofcheck in details:
- Adding Low level firmware commands support for creating ACLs
(Access Control Lists) Flow tables. ACLs are regular flow tables with
the only exception that they are bound to a specific e-Switch vport (VF)
and they can be one of two types
> egress ACL: filters traffic going from e-Switch to VF.
> ingress ACL: filters traffic going from VF to e-Switch.
- Ingress/Egress ACLs (per vport) for VF VST mode filtering.
- Ingress/Egress ACLs (per vport) for VF spoofcheck filtering.
- Ingress/Egress ACLs (per vport) configuration:
> Created only when at least one of (VST, spoofcheck) is configured.
> if (!spoofchk && !vst) allow all traffic. i.e. no ACLs.
> if (spoofchk && vst) allow only untagged traffic with smac=original mac \
sent from the VF.
> if (spoofchk && !vst) allow only traffic with smac=original mac sent from \
the VF. > if (!spoofchk && vst) allow only untagged traffic.
Trusted VF promiscuous and allmulti support in details:
- Added two flow groups for allmulti and promisc VFs to the e-Switch FDB table
> Allmulti group: One rule that forwards any mcast traffic coming from
either uplink or VFs/PF vports.
> Promisc group: One rule that forwards all unmatched traffic coming from \
uplink.
- Add vport context change event handling for promisc and allmulti
If VF is trusted respect the request and:
> if allmulti request: add the vport to the allmulti group.
and to all other L2 mcast address in the FDB table.
> if promisc request: add the vport to the promisc group.
> Note: A promisc VF can only see traffic that was not explicitly matched to
or requested by any other VF.

- Upon VF trust setting change we update vport context to refresh
allmulti/promisc or any trusted vf attributes that we didn't trust the
VF for before.

vport context updates , this will prevent contention with vport trust

Vport spin lock can be replaced with synchronize_irq() in the right
place, this will remove the need of locking inside irq context.
Locking in esw_enable_vport is not required since vport events are yet
to be enabled, and at esw_disable_vport it is sufficient to
synchronize_irq() to guarantee no further vport events handlers will be
scheduled.

Update the relevant flow steering device structs and commands to
support vport.
Update the flow steering core API to receive vport number.
Add ingress and egress ACL flow table name spaces.
Add ACL flow table support:
* ACL (Access Control List) flow table is a table that contains
only allow/drop steering rules.
* We have two types of ACL flow tables - ingress and egress.
* ACLs handle traffic sent from/to E-Switch FDB table, Ingress refers to
traffic sent from Vport to E-Switch and Egress refers to traffic sent
from E-Switch to vport.
* Ingress ACL flow table allow/drop rules is checked against traffic
sent from VF.
* Egress ACL flow table allow/drop rules is checked against traffic sent
to VF.

en_arfs.o should be compiled only if both CONFIG_MLX5_CORE_EN
and CONFIG_RFS_ACCEL are enabled. en_arfs calls to rps_may_expire_flow
which is compiled only if CONFIG_RFS_ACCEL is defined.
Move en_arfs.o compilation dependency to be under CONFIG_MLX5_CORE_EN
and wrap the en_arfs.c content with ifdef of CONFIG_RFS_ACCEL.

When probe bails out with an error, we try to unregister the
netdev before we have even registered it. Fix the goto statements
for that.

====================
cxgb4: mbox enhancements for cxgb4
This patch series checks for firmware errors when we are waiting for
mbox response in a loop and breaks out. When negative timeout is passed
to mailbox code, don't sleep. Negative timeout is passed only from
interrupt context.
This patch series has been created against net-next tree and includes
patches on cxgb4 driver.
We have included all the maintainers of respective drivers. Kindly review
the change and let us know in case of any review comments.

Check for firmware errors in the mailbox command loop and report
them differently rather than simply timing out when the firmware goes
belly up.
