The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox. The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.
Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases. In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.

====================
pull-request: bpf 2017-12-02
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a compilation warning in xdp redirect tracepoint due to
missing bpf.h include that pulls in struct bpf_map, from Xie.
2) Limit the maximum number of attachable BPF progs for a given
perf event as long as uabi is not frozen yet. The hard upper
limit is now 64 and therefore the same as with BPF multi-prog
for cgroups. Also add related error checking for the sample
BPF loader when enabling and attaching to the perf event, from
Yonghong.
3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log
case, so that the test case can always pass and not fail in
some environments due to too low default limit, also from
Yonghong.
4) Fix up a missing license header comment for kernel/bpf/offload.c,
from Jakub.
5) Several fixes for bpftool, among others a crash on incorrect
arguments when json output is used, error message handling
fixes on unknown options and proper destruction of json writer
for some exit cases, all from Quentin.

In rxrpc_release_sock() there may be no rx->local value to access, so we
can't unconditionally follow it to the rxrpc network namespace information
to poke the connection reapers.
Instead, use the socket's namespace pointer to find the namespace.
This unfixed code causes the following static checker warning:
net/rxrpc/af_rxrpc.c:898 rxrpc_release_sock()

====================
pull-request: can 2017-12-01
this is a pull for net consisting of nine patches.
The first three patches are by Jimmy Assarsson for the kvaser_usb driver
and add the missing free()s in some error path, a signed/unsigned
comparison and ratelimit the error messages in case of incomplete
messages. Oliver Stäbler's patch for the ti_hecc driver fix the napi
poll function's return value. The return values of the probe function of
the peak_canfd and peak_pci PCI drivers are fixed by Stephane Grosjean's
patch. Two patches by me for the flexcan driver update the
bugs/features/quirks overview table and fix the error state transition
for the VF610 SoC. The two patches by Martin Kelly for the mcba_usb
driver fix a typo and a device disconnect bug.

Merge tag 'at24-4.15-fixes-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-current
Please consider pulling the following fixes for v4.15. While it doesn't
fix any regression introduced in the v4.15 merge window, we have a
feature in at24 since linux v4.8 - reading the mac address block from
at24mac series - which turned out to be not working.
This pull request contains changes that fix it together with a patch
that hardens the read and write argument sanitization with
out-of-bounds checks that were missing.
The mss variable tracks the last max segment size sent to the TSO
engine. We do not update the hardware as long as we receive skb:s with
the same value in gso_size.
During a network device down/up cycle (mapped to stmmac_release() and
stmmac_open() callbacks) we issue a reset to the hardware and it
forgets the setting for mss. However we did not zero out our mss
variable so the next transmission of a gso packet happens with an
undefined hardware setting.
This triggers a hang in the TSO engine and eventuelly the netdev
watchdog will bark.

The current GSO skb size limit was copy&pasted over from the L3 path,
where it is needed due to a TSO limitation.
As L2 devices don't offer TSO support (and thus all GSO skbs are
segmented before they reach the driver), there's no reason to restrict
the stack in how large it may build the GSO skbs.

Using GSO with small MTUs currently results in a substantial throughput
regression - which is caused by how qeth needs to map non-linear skbs
into its IO buffer elements:
compared to a linear skb, each GSO-segmented skb effectively consumes
twice as many buffer elements (ie two instead of one) due to the
additional header-only part. This causes the Output Queue to be
congested with low-utilized IO buffers.
Fix this as follows:
If the MSS is low enough so that a non-SG GSO segmentation produces
order-0 skbs (currently ~3500 byte), opt out from NETIF_F_SG. This is
where we anticipate the biggest savings, since an SG-enabled
GSO segmentation produces skbs that always consume at least two
buffer elements.
Larger MSS values continue to get a SG-enabled GSO segmentation, since
1) the relative overhead of the additional header-only buffer element
becomes less noticeable, and
2) the linearization overhead increases.
With the throughput regression fixed, re-enable NETIF_F_SG by default to
reap the significant CPU savings of GSO.

Commit 5f78e29cee ("qeth: optimize IP handling in rx_mode callback")
reworked how secondary addresses are managed for qeth devices.
Instead of dropping & subsequently re-adding all addresses on every
ndo_set_rx_mode() call, qeth now keeps track of the addresses that are
currently registered with the HW.
On a ndo_set_rx_mode(), we thus only need to do (de-)registration
requests for the addresses that have actually changed.
On L3 devices, the lookup for IPv4 Multicast addresses checks the wrong
hashtable - and thus never finds a match. As a result, we first delete
*all* such addresses, and then re-add them again. So each set_rx_mode()
causes a short period where the IPv4 Multicast addresses are not
registered, and the card stops forwarding inbound traffic for them.
Fix this by setting the ->is_multicast flag on the lookup object, thus
enabling qeth_l3_ip_from_hash() to search the correct hashtable and
find a match there.

https://www.mail-archive.com/netdev@vger.kernel.org/msg187936.html
Eventually we figured out that it was a skb leak in handle_rx()
when sending packets to the VM. This usually happens when a guest
can not drain out vq as fast as vhost fills in, afterwards it sets
off the traffic jam and leaks skb(s) which occurs as no headcount
to send on the vq from vhost side.
This can be avoided by making sure we have got enough headcount
before actually consuming a skb from the batched rx array while
transmitting, which is simply done by moving checking the zero
headcount a bit ahead.

The current 'bnxt_shutdown' implementation only invokes
'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in
the path of power off (SYSTEM_POWER_OFF). While this may work in most
cases, it does not work in the smart NIC case, when Linux 'reboot'
command is initiated from the Linux that runs on the ARM cores of the
NIC card. In this particular case, Linux 'reboot' results in a system
'L3' level reset where the entire ARM and associated subsystems are
being reset, but at the same time, Nitro core is being kept in sane state
(to allow external PCIe connected servers to continue to work). Without
properly shutting down RoCE and freeing all associated resources, it
results in the ARM core to hang immediately after the 'reboot'
By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the
above issue

My bisect scripts starting running into build failures when trying to
compile 4.15-rc1 with the builds failing with things like:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:2078: error: Cannot parse struct or union!
The line in question is actually just a #define, but after some digging
it turns out that my scripts pass W=1 and since commit 3a025e1d1c
("Add optional check for bad kernel-doc comments") that results in
kernel-doc running on each source file. The file in question has a
badly formatted comment immediately before the #define:
/**
* struct brcmf_skbuff_cb reserves first two bytes in sk_buff::cb for
* bus layer usage.
*/
which causes the regex in dump_struct to fail (lack of braces following
struct declaration) and kernel-doc returns 1, which causes the build
to fail.
Fix the issue by always returning 0 from kernel-doc when invoked with
-none. It successfully generates no documentation, and prints out any
issues.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
The I2C device ID table entries have the .driver_data field set, but they
are not used in the driver so weren't set in the OF device table entries.

The ADC driver can trigger on either the timer or the lptim
trigger, but it only uses a Kconfig 'select' statement
to ensure that the first of the two is present. When the lptim
trigger is enabled as a loadable module, and the adc driver
is built-in, we now get a link error:
drivers/iio/adc/stm32-adc.o: In function `stm32_adc_get_trig_extsel':
stm32-adc.c:(.text+0x4e0): undefined reference to `is_stm32_lptim_trigger'
We could use a second 'select' statement and always have both
trigger drivers enabled when the adc driver is, but it seems that
the lptimer trigger was intentionally left optional, so it seems
better to keep it that way.
This adds a hack to use 'IS_REACHABLE()' rather than 'IS_ENABLED()',
which avoids the link error, but instead leads to the lptimer trigger
not being used in the broken configuration. I've added a runtime
warning for this case to help users figure out what they did wrong
if this should ever be done by accident.
