GEN8 never freed the PPGTT struct. As GEN8 doesn't use full PPGTT, the
leak is small and only found on a module reload. ie. I don't think this
needs to go to stable.
v2: The very naive, kfree in gen8 ppgtt cleanup, is subject to a double
free on PPGTT initialization failure. (Spotted by Imre). Instead this
patch pulls the ppgtt struct freeing out of the cleanup and leaves it to
the allocators/callers or the one doing the last kref_put as in standard
convention

At one time it was expected to be called in multiple places by kref_put.
At the current time however, it is all contained within
i915_gem_context.c.
This patch makes an upcoming required addition a bit nicer since it too
doesn't need to be defined in a header file.

On SNB we set up WaSetupGtModeTdRowDispatch:snb early in
gen6_init_clock_gating(). That sets a bit in the GEN6_GT_MODE register.
However later we go and disable all the bits in the same register. And
then we go on to set some other bit. So apparently we never actually
implemented this workaround since the "disable all bits" part was there
already before the w/a got supposedly implemented.
These are the relevant commits:

Author: Ben Widawsky <ben@bwidawsk.net>
Date: Wed Oct 3 19:34:24 2012 -0700
drm/i915: Fix GT_MODE default value
So, let's drop the "disable all bits" part, move both writes to
closer proxomity to each other, and name the WIZ hashing bits
appropriately. BSpec is still a bit confused how the bits should
actually be interpreted, but I took the the description for the
high bit since the low bit part only lists values for a single bit.
Also add a comment about our choice of WIZ hashing mode.

If a module fails to add its tracepoints due to module tainting, do not
create the module event infrastructure in the debugfs directory. As the events
will not work and worse yet, they will silently fail, making the user wonder
why the events they enable do not display anything.
Having a warning on module load and the events not visible to the users
will make the cause of the problem much clearer.

Commit 55494bf2947dccdf2 ("dm snapshot: use dm-bufio") broke snapshots.
Before that 3.14-rc1 commit, loading a snapshot's list of exceptions
involved reading exception areas one by one into ps->area and inserting
those exceptions into the hash table. Commit 55494bf2947dccdf2 changed
it so that dm-bufio with prefetch is used to load exceptions in batchs.
Exceptions are loaded correctly, but ps->area is left uninitialized.
When a new exception is allocated, it is stored in this uninitialized
ps->area which will be written to the disk. This causes metadata
corruption.
Fix this corruption by copying the last area that was read via dm-bufio
into ps->area.

Macvlan currently inherits all of its features from the lower
device. When lower device disables offload support, this causes
macvlan to disable offload support as well. This causes
performance regression when using macvlan/macvtap in bridge
mode.
It can be easily demonstrated by creating 2 namespaces using
macvlan in bridge mode and running netperf between them:
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.0.0.1 () port 0 AF_INET

Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 20.00 1204.61
To restore the performance, we add software offload features
to the list of "always_on" features for macvlan. This way
when a namespace or a guest using macvtap initially sends a
packet, this packet will not be segmented at macvlan level.
It will only be segmented when macvlan sends the packet
to the lower device.

regulatory domain updates failed and two fixes for VHT associations: one
to not disconnect immediately when the AP uses more bandwidth than the
new regdomain would allow after a change due to association country
information getting used, and one for an issue in the code where
mac80211 doesn't correctly ignore a reserved field and then uses an HT
instead of VHT association."
For the iwlwifi bits, Emmanuel says:
"Johannes fixes a long standing bug in the AMPDU status reporting.
Max fixes the listen time which was way too long and causes trouble
to several APs."

RFC4895 introduced AUTH chunks for SCTP; during the SCTP
handshake RANDOM; CHUNKS; HMAC-ALGO are negotiated (CHUNKS
being optional though):
---------- INIT[RANDOM; CHUNKS; HMAC-ALGO] ---------->
<------- INIT-ACK[RANDOM; CHUNKS; HMAC-ALGO] ---------
-------------------- COOKIE-ECHO -------------------->
<-------------------- COOKIE-ACK ---------------------
A special case is when an endpoint requires COOKIE-ECHO
chunks to be authenticated:
---------- INIT[RANDOM; CHUNKS; HMAC-ALGO] ---------->
<------- INIT-ACK[RANDOM; CHUNKS; HMAC-ALGO] ---------
------------------ AUTH; COOKIE-ECHO ---------------->
<-------------------- COOKIE-ACK ---------------------
RFC4895, section 6.3. Receiving Authenticated Chunks says:
The receiver MUST use the HMAC algorithm indicated in
the HMAC Identifier field. If this algorithm was not
specified by the receiver in the HMAC-ALGO parameter in
the INIT or INIT-ACK chunk during association setup, the
AUTH chunk and all the chunks after it MUST be discarded
and an ERROR chunk SHOULD be sent with the error cause
defined in Section 4.1. [...] If no endpoint pair shared
key has been configured for that Shared Key Identifier,
all authenticated chunks MUST be silently discarded. [...]
When an endpoint requires COOKIE-ECHO chunks to be
authenticated, some special procedures have to be followed
because the reception of a COOKIE-ECHO chunk might result
in the creation of an SCTP association. If a packet arrives
containing an AUTH chunk as a first chunk, a COOKIE-ECHO
chunk as the second chunk, and possibly more chunks after
them, and the receiver does not have an STCB for that
packet, then authentication is based on the contents of
the COOKIE-ECHO chunk. In this situation, the receiver MUST
authenticate the chunks in the packet by using the RANDOM
parameters, CHUNKS parameters and HMAC_ALGO parameters
obtained from the COOKIE-ECHO chunk, and possibly a local
shared secret as inputs to the authentication procedure
specified in Section 6.3. If authentication fails, then
the packet is discarded. If the authentication is successful,
the COOKIE-ECHO and all the chunks after the COOKIE-ECHO
MUST be processed. If the receiver has an STCB, it MUST
process the AUTH chunk as described above using the STCB
from the existing association to authenticate the
COOKIE-ECHO chunk and all the chunks after it. [...]
Commit bbd0d59809f9 introduced the possibility to receive
and verification of AUTH chunk, including the edge case for
authenticated COOKIE-ECHO. On reception of COOKIE-ECHO,
the function sctp_sf_do_5_1D_ce() handles processing,
unpacks and creates a new association if it passed sanity
checks and also tests for authentication chunks being
present. After a new association has been processed, it
invokes sctp_process_init() on the new association and
walks through the parameter list it received from the INIT
chunk. It checks SCTP_PARAM_RANDOM, SCTP_PARAM_HMAC_ALGO
and SCTP_PARAM_CHUNKS, and copies them into asoc->peer
meta data (peer_random, peer_hmacs, peer_chunks) in case
sysctl -w net.sctp.auth_enable=1 is set. If in INIT's
SCTP_PARAM_SUPPORTED_EXT parameter SCTP_CID_AUTH is set,
peer_random != NULL and peer_hmacs != NULL the peer is to be
assumed asoc->peer.auth_capable=1, in any other case
asoc->peer.auth_capable=0.
Now, if in sctp_sf_do_5_1D_ce() chunk->auth_chunk is
available, we set up a fake auth chunk and pass that on to
sctp_sf_authenticate(), which at latest in
sctp_auth_calculate_hmac() reliably dereferences a NULL pointer
at position 0..0008 when setting up the crypto key in
crypto_hash_setkey() by using asoc->asoc_shared_key that is
NULL as condition key_id == asoc->active_key_id is true if
the AUTH chunk was injected correctly from remote. This
happens no matter what net.sctp.auth_enable sysctl says.
The fix is to check for net->sctp.auth_enable and for
asoc->peer.auth_capable before doing any operations like
sctp_sf_authenticate() as no key is activated in
sctp_auth_asoc_init_active_key() for each case.
Now as RFC4895 section 6.3 states that if the used HMAC-ALGO
passed from the INIT chunk was not used in the AUTH chunk, we
SHOULD send an error; however in this case it would be better
to just silently discard such a maliciously prepared handshake
as we didn't even receive a parameter at all. Also, as our
endpoint has no shared key configured, section 6.3 says that
MUST silently discard, which we are doing from now onwards.
Before calling sctp_sf_pdiscard(), we need not only to free
the association, but also the chunk->auth_chunk skb, as
commit bbd0d59809f9 created a skb clone in that case.
I have tested this locally by using netfilter's nfqueue and
re-injecting packets into the local stack after maliciously
modifying the INIT chunk (removing RANDOM; HMAC-ALGO param)
and the SCTP packet containing the COOKIE_ECHO (injecting
AUTH chunk before COOKIE_ECHO). Fixed with this patch applied.

This patch fixes a CPDMA RX Descriptor leak that occurs after taking
the interface down when the CPSW is in Dual MAC mode. Previously
the CPSW_ALE port was left open up which causes packets to be received
and processed by the RX interrupt handler and were passed to the
non active network interface where they were ignored.
The fix is for the slave_stop function of the selected interface
to disable the respective CPSW_ALE Port from forwarding packets. This
blocks traffic from being received on the inactive interface.

RTT may be bogus with tall loss probe (TLP) when a packet
is retransmitted and latter (s)acked without TCPCB_SACKED_RETRANS flag.
For example, TLP calls __tcp_retransmit_skb() instead of
tcp_retransmit_skb(). The skb timestamps are updated but the sacked
flag is not marked with TCPCB_SACKED_RETRANS. As a result we'll
get bogus RTT in tcp_clean_rtx_queue() or in tcp_sacktag_one() on
spurious retransmission.
The fix is to apply the sticky flag TCP_EVER_RETRANS to enforce Karn's
check on RTT sampling. However this will disable F-RTO if timeout occurs
after TLP, by resetting undo_marker in tcp_enter_loss(). We relax this
check to only if any pending retransmists are still in-flight.

We need to read the correct register, not a register that doesn't exist
and will trigger "Unclaimed register" messages when we touch it.
Also rearrange the checks in an attempt to prevent this error from
happening again.

We reserve the space for the power context in stolen memory at a fixed
address from a delayed work. This races with the subsequent driver
init/resume code which could allocate something at that address, so the
reservation for the power context fails. Reserve the space up-front, so
this can't happen. This also adds a missing struct_mutex lock around the
stolen allocation, which wasn't taken in the delayed work path.

This patch does a cleanup about the thermal zone govenor,
setting and make the following rule.
1. For thermal zone devices that are registered w/o tz->tzp,
they can use the default thermal governor only.
2. For thermal zone devices w/ governor name specified in
tz->tzp->governor_name, we will use the default govenor
if the governor specified is not available at the moment,
and update tz->governor when the matched governor is registered.
This also fixes a problem that OF registered thermal zones
are running with no governor.

In initialization, if the cooling device is initialized at
max cooling state, and the thermal zone temperature is below
the first trip point, then the cooling state can't be updated
to the right state, untill the first trip point be triggered.
To fix this issue, allow first update of cooling device state
during registration, initialized "updated" device field as
"false" (instead of "true").

Commit beeb5a1e (thermal: rcar-thermal: Enable driver compilation with COMPILE_TEST)
broke build on archs wihout io memory.
On archs like S390 or um this driver cannot build nor work.
Make it depend on HAS_IOMEM to bypass build failures.

The thermal zone type should not include an instance number. Otherwise
each zone is considered a different type and the thermal-to-hwmon
bridge fails to group them all in a single hwmon device.
I also changed the type to "x86_pkg_temp", because "pkg" was too
generic, and other thermal drivers use an underscore, not a dash, as
a separator. Or maybe "cpu_pkg_temp" would be better?

The temperature value reported by x86_pkg_temp_thermal is already
reported by the coretemp driver. So, do not expose this thermal zone
as a hwmon device, because it would be redundant.

In commit e2d265d3b587 (canfd: add support for CAN FD in CAN_RAW sockets)
CAN FD frames with a payload length up to 8 byte are passed to legacy
sockets where the CAN FD support was not enabled by the application.
After some discussions with developers at a fair this well meant feature
leads to confusion as no clean switch for CAN / CAN FD is provided to the
application programmer. Additionally a compatibility like this for legacy
CAN_RAW sockets requires some compatibility handling for the sending, e.g.
make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?).
This will become a mess when people start to develop applications with
real CAN FD hardware. This patch reverts the bad compatibility code
together with the documentation describing the removed feature.

This patch factors out freeze and unfreeze of the CAN core into seperate
functions. Experiments have shown that the transition from and to freeze mode
may take several microseconds, especially the time entering the freeze mode
depends on the current bitrate.
This patch adds a while loop which polls the Freeze Mode ACK bit (FRZ_ACK) that
indicates a successfull mode change. If the function runs into a timeout a
error value is returned.
