In commit:
3078cde7 can: at91_can: add dt support
device tree support was added to the at91_can driver. In this commit the
mapping of device to driver data was mixed up. This results in the sam9x5
parameters being used for the sam9263 and the workaround for the broken mailbox
0 on the sam9263 not being activated.
This patch fixes the broken platform_device_id table.

The current implemetation of of_match_device() relies that the of_device_id
table in the driver is sorted from most specific to least specific compatible.
Without this patch the mx28 is detected as the less specific p1010. This leads
to a p1010 specific workaround is activated on the mx28, which is not needed.

abort pending TX
In patch
0d1862e can: flexcan: fix flexcan_chip_start() on imx6
the loop in flexcan_chip_start() that iterates over all mailboxes after the
soft reset of the CAN core was removed. This loop put all mailboxes (even the
ones marked as reserved 1...7) into EMPTY/INACTIVE mode. On mailboxes 8...63,
this aborts any pending TX messages.
After a cold boot there is random garbage in the mailboxes, which leads to
spontaneous transmit of CAN frames during first activation. Further if the
interface was disabled with a pending message (usually due to an error
condition on the CAN bus), this message is retransmitted after enabling the
interface again.
This patch fixes the regression by:
1) Limiting the maximum number of used mailboxes to 8, 0...7 are used by the RX
FIFO, 8 is used by TX.
2) Marking the TX mailbox as EMPTY/INACTIVE, so that any pending TX of that
mailbox is aborted.

Most of the bits are for iwlwifi -- Johannes says:
"I have a fix for WoWLAN/D3, a PCIe device fix, we're removing a
warning, there's a fix for RF-kill while scanning (which goes together
with a mac80211 fix) and last but not least we have many new PCI IDs."
Also for iwlwifi is a patch from Johannes to correct some merge damage
that crept into the tree before the last merge window.
On top of that, Felix Fietkau sends an ath9k patch to avoid a Tx

"Excess delays when transmitting TOE=1 large frames".
The impact is that frames lager than 2500-bytes for which

may see excess delay before start of transmission.

Use the macros and defines from mpc85xx.h to simplify
and prevent errors in identifying a mpc85xx based SoC
for errata detection.
This should help enabling (and identifying) workarounds
for various mpc85xx based chips and revisions.
For instance, express MPC8548 Rev.2 as:
(SVR_SOC_VER(svr) == SVR_8548) && (SVR_REV(svr) == 0x20)
instead of:
(pvr == 0x80210020 && mod == 0x8030 && rev == 0x0020)

A002 is still in "no plans to fix" state, and applies to all
the current P1/P2 parts as well, so it's resonable to enable
its workaround by default, for all the soc's with etsec.
The impact of not enabling this workaround for affected parts
is that under certain conditons (runt frames or even frames
with RX error detected at PHY level) during controller reset,
the controller might fail to indicate Rx reset (GRS) completion.

Steffen Klassert says:
====================
1) We used the wrong netlink attribute to verify the
lenght of the replay window on async events. Fix this by
using the right netlink attribute.
2) Policy lookups can not match the output interface on forwarding.
Add the needed informations to the flow informations.
3) We update the pmtu when we receive a ICMPV6_DEST_UNREACH message
on IPsec with ipv6. This is wrong and leads to strange fragmented
packets, only ICMPV6_PKT_TOOBIG messages should update the pmtu.
Fix this by removing the ICMPV6_DEST_UNREACH check from the IPsec
protocol error handlers.
4) The legacy IPsec anti replay mechanism supports anti replay
windows up to 32 packets. If a user requests for a bigger
anti replay window, we use 32 packets but pretend that we use
the requested window size. Fix from Fan Du.
5) If asynchronous events are enabled and replay_maxdiff is set to
zero, we generate an async event for every received packet instead
of checking whether a timeout occurred. Fix from Thomas Egerer.
6) Policies need a refcount when the state resolution timer is armed.
Otherwise the timer can fire after the policy is deleted.
7) We might dreference a NULL pointer if the hold_queue is empty,
add a check to avoid this.

The crash reported and investigated in commit 5f4513 turned out to be
caused by a change to the read interface on newer (2012) SMCs.
Tests by Chris show that simply reading the data valid line is enough
for the problem to go away. Additional tests show that the newer SMCs
no longer wait for the number of requested bytes, but start sending
data right away. Apparently the number of bytes to read is no longer
specified as before, but instead found out by reading until end of
data. Failure to read until end of data confuses the state machine,
which eventually causes the crash.
As a remedy, assuming bit0 is the read valid line, make sure there is
nothing more to read before leaving the read function.
Tested to resolve the original problem, and runtested on MBA3,1,
MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on
machines before 2012.

__ieee80211_scan_completed is called from a worker. This
means that the following flow is possible.
* driver calls ieee80211_scan_completed
* mac80211 cancels the scan (that is already complete)
* __ieee80211_scan_completed runs
When scan_work will finally run, it will see that the scan
hasn't been aborted and might even trigger another scan on
another band. This leads to a situation where cfg80211's
scan is not done and no further scan can be issued.
Fix this by setting a new flag when a HW scan is being
cancelled so that no other scan will be triggered.

The unpacked_lun field in the SCSI target tracepoints should be
initialized with cmd->orig_fe_lun rather than cmd->se_lun->unpacked_lun
for two reasons:
- most importantly, if we are in the cmd_complete tracepoint
returning a check condition due to no LUN found, cmd->se_lun will
be NULL and we'll crash trying to dereference it.
- also, in any case, cmd->se_lun->unpacked_lun is an internal index
into the target's internal set of LUNs; cmd->orig_fe_lun is much
more useful and interesting, since it's the value the initiator
actually sent.

Steinar reported FQ pacing was not working for UDP flows.
It looks like the initial sk->sk_pacing_rate value of 0 was
a wrong choice. We should init it to ~0U (unlimited)
Then, TCA_FQ_FLOW_DEFAULT_RATE should be removed because it makes
no real sense. The default rate is really unlimited, and we

Unlike ipv4, the struct member hlen holds the length of the GRE and ipv6
headers. This length is also counted in dev->hard_header_len.
Perhaps, it's more clean to modify the hlen to count only the GRE header
without ipv6 header as the variable name suggest, but the simple way to fix
this without regression risk is simply modify the calculation of the limit
in ip6gre_tunnel_change_mtu function.

If a guest is destroyed without transitioning its frontend to CLOSED,
the domain becomes a zombie as netback was not grant unmapping the
shared rings.
When removing a VIF, transition the backend to CLOSED so the VIF is

Fix race conditions in mrf24j40 interrupts
After testing with the betas of this patchset, it's been rebased and is

David Hauweele noticed that the mrf24j40 would hang arbitrarily after some
period of heavy traffic. Two race conditions were discovered, and the
driver was changed to use threaded interrupts, since the enable/disable of
interrupts in the driver has recently been a lighning rod whenever issues
arise related to interrupts (costing engineering time), and since threaded
interrupts are the right way to do it.

The mrf24j40 generates level interrupts. There are rare cases where it
appears that the interrupt line never gets de-asserted between interrupts,
causing interrupts to be lost, and causing a hung device from the driver's
perspective. Switching the driver to interpret these interrupts as
level-triggered fixes this issue.
