commit 1d6f8c5bac93cceb2d4ac8e6331050652004d802 upstream.
Commit 1f27dbd8265d ("platform/x86: GPD pocket fan: Allow somewhat
lower/higher temperature limits") changed the module-param sanity check
to accept temperature limits between 20 and 90 degrees celcius.
But the error message printed when the module params are outside this
range was not updated. This commit updates the error message to match
the new min and max value for the temp-limits.

[ Upstream commit 3554e54a46125030c534820c297ed7f6c3907e24 ]
The driver is designed to drop Rx packets and reclaim the buffers
when an allocation fails, and the network interface needs to safely
handle this packet loss. Therefore, an allocation failure of Rx
SKBs is relatively benign.
However, the output of the warning message occurs with a high
scheduling priority that can cause excessive jitter/latency for
other high priority processing.
This commit suppresses the warning messages to prevent scheduling
problems while retaining the failure count in the statistics of
the network interface.

This reverts commit 3df85a1ae51f6b256982fe9d17c2dc5bfb4cc402.
The reverted commit says "It's possible to release the node ID
immediately when fwnode_remove_software_node() is called, no need to
wait for software_node_release() with that." However, releasing the node
ID before waiting for software_node_release() to be called causes the
node ID to be released before the kobject and the underlying sysfs
entry; this means there is a period of time where a sysfs entry exists
that is associated with an unallocated node ID.
Once consequence of this is that there is a race condition where it is
possible to call fwnode_create_software_node() with no parent node
specified (NULL) and have it fail with -EEXIST because the node ID that
was assigned is still associated with a stale sysfs entry that hasn't
been cleaned up yet.
Although it is difficult to reproduce this race condition under normal
conditions, it can be deterministically reproduced with the following
minconfig on UML:
CONFIG_KUNIT_DRIVER_PE_TEST=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_OBJECTS=y
CONFIG_DEBUG_OBJECTS_TIMERS=y
CONFIG_DEBUG_KOBJECT_RELEASE=y
CONFIG_KUNIT=y
Running the tests with this configuration causes the following failure:
<snip>
kobject: 'node0' ((____ptrval____)): kobject_release, parent (____ptrval____) (delayed 400)
ok 1 - pe_test_uints

[ Upstream commit ecaeceb8a8a145d93c7e136f170238229165348f ]
The driver is designed to drop Rx packets and reclaim the buffers
when an allocation fails, and the network interface needs to safely
handle this packet loss. Therefore, an allocation failure of Rx
SKBs is relatively benign.
However, the output of the warning message occurs with a high
scheduling priority that can cause excessive jitter/latency for
other high priority processing.
This commit suppresses the warning messages to prevent scheduling
problems while retaining the failure count in the statistics of
the network interface.

commit 30b2f0be23fb40e58d0ad2caf8702c2a44cda2e1 upstream.
commit 08a5bdde3812 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED")
Fixed a bug where we failed to take into account a
nullfunc frame can be either non-QoS or QoS. It turns out
there is at least one more bug in
ieee80211_sta_tx_notify(), introduced in
commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing"),
where we forgot to check for the QoS variant and so
assumed the QoS nullfunc frame never went out
Fix this by adding a helper ieee80211_is_any_nullfunc()
which consolidates the check for non-QoS and QoS nullfunc
frames. Replace existing compound conditionals and add a
couple more missing checks for QoS variant.

commit a8ff78f7f773142eb8a8befe5a95dd6858ebd635 upstream.
Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci
in MTRR. This will cause the system to hang during boot. If possible,
this bug could be corrected with a firmware update.
This patch use devm_ioremap_uc to overwrite/ignore the MTRR settings
by forcing the use of strongly uncachable pages for intel-lpss.
The BIOS bug is present on Dell XPS 13 7390 2-in-1:

From: Paulo Alcantara <[email protected]>
[ Upstream commit 65303de829dd6d291a4947c1a31de31896f8a060 ]
This disables tcon re-use for DFS shares.
tcon->dfs_path stores the path that the tcon should connect to when
doing failing over.
If that tcon is used multiple times e.g. 2 mounts using it with
different prefixpath, each will need a different dfs_path but there is
only one tcon. The other solution would be to split the tcon in 2
tcons during failover but that is much harder.
tcons could not be shared with DFS in cifs.ko because in a
DFS namespace like:
//domain/dfsroot -> /serverA/dfsroot, /serverB/dfsroot
//serverA/dfsroot/link -> /serverA/target1/aa/bb
//serverA/dfsroot/link2 -> /serverA/target1/cc/dd
you can see that link and link2 are two DFS links that both resolve to
the same target share (/serverA/target1), so cifs.ko will only contain a
single tcon for both link and link2.
The problem with that is, if we (auto)mount "link" and "link2", cifs.ko
will only contain a single tcon for both DFS links so we couldn't
perform failover or refresh the DFS cache for both links because
tcon->dfs_path was set to either "link" or "link2", but not both --
which is wrong.

[ Upstream commit b94e164759b82d0c1c80d4b1c8f12c9bee83f11d ]
The HDMI?_SEL register maps up to four stereo SSI data lanes onto the
sdata[0..3] inputs of the HDMI output block. The upper half of the
register contains four blocks of 4 bits, with the most significant
controlling the sdata3 line and the least significant the sdata0 line.
The shift calculation has an off-by-one error, causing the parent SSI to
be mapped to sdata3, the first multi-SSI child to sdata0 and so forth.
As the parent SSI transmits the stereo L/R channels, and the HDMI core
expects it on the sdata0 line, this causes no audio to be output when
playing stereo audio on a multichannel capable HDMI out, and
multichannel audio has permutated channels.
Fix the shift calculation to map the parent SSI to sdata0, the first
child to sdata1 etc.

[ Upstream commit d94ea5319813658ad5861d161ae16a194c2abf88 ]
Currently the calculation of max packet size limit for IN endpoints is
too restrictive. This prevents a matching of a capable hardware endpoint
during configuration. Below is the minimum recommended HW configuration
to support a particular endpoint setup from the databook:
For OUT endpoints, the databook recommended the minimum RxFIFO size to
be at least 3x MaxPacketSize + 3x setup packets size (8 bytes each) +
clock crossing margin (16 bytes).
For IN endpoints, the databook recommended the minimum TxFIFO size to be
at least 3x MaxPacketSize for endpoints that support burst. If the
endpoint doesn't support burst or when the device is operating in USB
2.0 mode, a minimum TxFIFO size of 2x MaxPacketSize is recommended.
Base on these recommendations, we can calculate the MaxPacketSize limit
of each endpoint. This patch revises the IN endpoint MaxPacketSize limit
and also sets the MaxPacketSize limit for OUT endpoints.

commit 12dfd78e3a74825e6f0bc8df7ef9f938fbc6bfe3 upstream.
When starting shutdown in sctp_sf_do_dupcook_a(), get the value for
SHUTDOWN Cumulative TSN Ack from the new association, which is
reconstructed from the cookie, instead of the old association, which
the peer doesn't have anymore.
Otherwise the SHUTDOWN is either ignored or replied to with an ABORT
by the peer because CTSN Ack doesn't match the peer's Initial TSN.

[ Upstream commit 83a196773b8bc6702f49df1eddc848180e350340 ]
Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

[ Upstream commit a09fb3f28a60ba3e928a1fa94b0456780800299d ]
The parent SSI of a multi-SSI setup must be fully setup, started and
stopped since it is also part of the playback/capture setup. So only
skip the SSI (as per commit 203cdf51f288 ("ASoC: rsnd: SSI parent cares
SWSP bit") and commit 597b046f0d99 ("ASoC: rsnd: control SSICR::EN
correctly")) if the SSI is parent outside of a multi-SSI setup.

Compiled and booted on my test system. I am seeing the following
regression in dmesg and with a new emergency message.
Initramfs unpacking failed: Decoding failed
I don't know why yet. I will debug and let you know.

At a guess: you upgraded to Ubuntu 20.04, and the default initramfs
compression changed to lz4. Or something like that.

Right, I remembered I ran into a similar problem after upgrading to
19.10 and went looking for info. instead of doing bisect.
That is what I found in the following thread:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1835660
Oddly it started showing up before I upgraded on Ubuntu 19.10.

Sounds like a reasonable guess. I looked into the 4.9.y changes since
v4.9.222, and nothing in there even remotely points to an initramfs
related change.
