platform/x86: silead_dmi: Fix GP-electronic T701 entry
The GP-electronic T701 has its LCD panel mounted upside-down, initially
my plan was to fix this by transparently rotating the image in the i915
driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but
that approach has been rejected instead the kernel will now export
a "panel orientation" property on the drm-connector for the panel and
let userspace deal with it.
But userspace expects the touchscreen coordinates to match the panel
coordinates *before* applying any rotation, so now that we no longer hide
the upside-down-ness of the LCD panel from userspace the coordinates being
generated are wrong and we need to apply a rotation of 180 degrees to the
coordinates to fix this.

When tested, on lifting the left edge, x values became increasingly negative

This was compensated by adding an entry for this device in hp_accel.c

Ev Kontsevoy reported that he can't see the presence of
"/proc/sys/kernel/sched_itmt_enabled" on i9-7900x with Asrock x299
Taichi system even if he enabled "Turbo 3.0" in the BIOS.
The problem is that even if one core max is 200MHz more than others, the
current implementation couldn't enumerate that with the way the system
is configured.
The system by default configured for legacy mode (no HWP or speed shift
technology), in this mode only way we can enumerate via the mail box
interface as implemented in this driver. We were planing to only use
this driver for Broadwell, but we need to extend this because some
Skylake system has same issue as Braodwell systems.
On this system BIOS allows to change to HWP mode, where we expect that
we can enumerate favored core with ACPI-CPPC. But on this system the
core priority is 0xff for all cores in CPPC object. So this is not an
option.
Hence this change allows Skylake systems to be enumerate favored core
similar to Broadwell in legacy mode.

On the affected platform (for which priv->array is NULL), add a new

notify_handler(), outside the wakeup mode this time, which allows
reporting the power button press event and triggers the suspend. Also
catch and ignore the corresponding power button release notification

that can force the controller awake. This is offered via a ACPI-WMI
interface intended to be manipulated by a userspace utility.
This mechanism is provided by Intel to OEMs to include in BIOS.
It uses an industry wide GUID that is populated in a separate _WDG
entry with no binary MOF.
This interface allows software such as fwupd to wake up thunderbolt
controllers to query the firmware version or flash new firmware.

firmware: Restore support for built-in firmware
Commit
5620a0d1aac ("firmware: delete in-kernel firmware") removed the
entire firmware directory. Unfortunately it thereby also removed the

This restores the ability to build firmware directly into the kernel by
pruning the original Makefile to the necessary minimum. The default for

sctp: fix an use-after-free issue in sctp_sock_dump
Commit
86fdb3448cc1 ("sctp: ensure ep is not destroyed before doing the
dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep
with holding sock and sock lock.
But Paolo noticed that endpoint could be destroyed in sctp_rcv without
sock lock protection. It means the use-after-free issue still could be
triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks
!ep, although it's pretty hard to reproduce.
I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close
and sctp_sock_dump long time.
This patch is to add another param cb_done to sctp_for_each_transport
and dump ep->assocs with holding tsp after jumping out of transport's
traversal in it to avoid this issue.
It can also improve sctp diag dump to make it run faster, as no need
to save sk into cb->args[5] and keep calling sctp_for_each_transport
any more.
This patch is also to use int * instead of int for the pos argument
in sctp_for_each_transport, which could make postion increment only
in sctp_for_each_transport and no need to keep changing cb->args[2]
in sctp_sock_filter and sctp_sock_dump any more.

tcp: update skb->skb_mstamp more carefully
liujian reported a problem in TCP_USER_TIMEOUT processing with a patch
in tcp_probe_timer() :
https://www.spinics.net/lists/netdev/msg454496.html
After investigations, the root cause of the problem is that we update
skb->skb_mstamp of skbs in write queue, even if the attempt to send a
clone or copy of it failed. One reason being a routing problem.
This patch prevents this, solving liujian issue.
It also removes a potential RTT miscalculation, since
__tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with
TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has
been changed.
A future ACK would then lead to a very small RTT sample and min_rtt
would then be lowered to this too small value.

net: ipv4: fix l3slave check for index returned in IP_PKTINFO
rt_iif is only set to the actual egress device for the output path. The
recent change to consider the l3slave flag when returning IP_PKTINFO
works for local traffic (the correct device index is returned), but it
broke the more typical use case of packets received from a remote host
always returning the VRF index rather than the original ingress device.
Update the fixup to consider l3slave and rt_iif actually getting set.

net: smsc911x: Quieten netif during suspend
If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.
E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock. If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.
As this is a race condition with a small time window, it is not so easy
to trigger at will. Using pm_test may increase your chances:
# echo 0 > /sys/module/printk/parameters/console_suspend
# echo platform > /sys/power/pm_test
# echo mem > /sys/power/state
To fix this, make sure the network interface is quietened during

minor reason, David Woodhouse didn't send the pull request at that
point in time, and everyone forgot about this.
The topic came up in the hallway track at the Plumbers conference this
week, so here's a single patch that drops the whole firmware tree. The
last firmware update was back in 2013, and all distros have been using
linux-firmware instead since at least that year, if not before. The
only commits to that directory since 2013 was some kbuild fixups for
various build tool issues.
So lets finally drop this, we don't need to lug them around in the

Merge branch 'zstd-minimal' of git://git./linux/kernel/git/mason/linux-btrfs
Pull zstd support from Chris Mason:
"Nick Terrell's patch series to add zstd support to the kernel has been
floating around for a while. After talking with Dave Sterba, Herbert
and Phillip, we decided to send the whole thing in as one pull
request.
zstd is a big win in speed over zlib and in compression ratio over
lzo, and the compression team here at FB has gotten great results
using it in production. Nick will continue to update the kernel side
with new improvements from the open source zstd userland code.
Nick has a number of benchmarks for the main zstd code in his lib/zstd
commit:
I ran the benchmarks on a Ubuntu 14.04 VM with 2 cores and 4 GiB
of RAM. The VM is running on a MacBook Pro with a 3.1 GHz Intel
Core i7 processor, 16 GB of RAM, and a SSD. I benchmarked using
`silesia.tar` [3], which is 211,988,480 B large. Run the following
commands for the benchmark:
sudo modprobe zstd_compress_test
sudo mknod zstd_compress_test c 245 0
sudo cp silesia.tar zstd_compress_test
The time is reported by the time of the userland `cp`.
The MB/s is computed with
1,536,217,008 B / time(buffer size, hash)
which includes the time to copy from userland.
The Adjusted MB/s is computed with
1,536,217,088 B / (time(buffer size, hash) - time(buffer size, none)).
The memory reported is the amount of memory the compressor
requests.

I benchmarked zstd decompression using the same method on the same
machine. The benchmark file is located in the upstream zstd repo
under `contrib/linux-kernel/zstd_decompress_test.c` [4]. The
memory reported is the amount of memory required to decompress
data compressed with the given compression level. If you know the
maximum size of your input, you can reduce the memory usage of
decompression irrespective of the compression level.

instruction type field of op.type rather than the whole thing,
