Subject: [PATCH] drm/panel: rocktech-jh057n00900: Rename the driver to st7703
This rename is done so that the driver matches the name of the
display controller and in preparation for adding support for more
panels to the driver.
This is just a basic file rename, with no code changes.

The reset pin is inverted, so if we don't assert reset, the actual gpio
will be high and may keep driving the IO port of the panel.

This is done so that code that's not specific to a particular
jh057n panel is named after the controller. Functions specific
to the panel are kept named after the panel.

Subject: [PATCH] dt-bindings: panel: Add compatible for Xingbangda XBD599
panel
Xingbangda XBD599 is a 5.99" 720x1440 MIPI-DSI LCD panel. It is based on
Sitronix ST7703 LCD controller just like rocktech,jh057n00900. It is
used in PinePhone.
Add a compatible for it.

Subject: [PATCH] platform/x86: thinkpad_acpi: lap or desk mode interface
Newer Lenovo Thinkpad platforms have support to identify whether the
system is on-lap or not using an ACPI DYTC event from the firmware.
This patch provides the ability to retrieve the current mode via sysfs
entrypoints and will be used by userspace for thermal mode and WWAN
functionality

+sysfs: dytc_lapmode
+
+Newer thinkpads and mobile workstations have the ability to determine if
+the device is in deskmode or lapmode. This feature is used by user space
+to decide if WWAN transmission can be increased to maximum power and is
+also useful for understanding the different thermal modes available as
+they differ between desk and lap mode.
+
+The property is read-only. If the platform doesn't have support the sysfs
+class is not created.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] selinux: allow reading labels before policy is loaded
This patch does for `getxattr` what commit 3e3e24b42043 ("selinux: allow
labeling before policy is loaded") did for `setxattr`; it allows
querying the current SELinux label on disk before the policy is loaded.
One of the motivations described in that commit message also drives this
patch: for Fedora CoreOS (and eventually RHEL CoreOS), we want to be
able to move the root filesystem for example, from xfs to ext4 on RAID,
on first boot, at initrd time.[1]
Because such an operation works at the filesystem level, we need to be
able to read the SELinux labels first from the original root, and apply
them to the files of the new root. The previous commit enabled the
second part of this process; this commit enables the first part.

From 073d0552ead5bfc7a3a9c01de590e924f11b5dd2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] xen/events: avoid removing an event channel while handling it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Today it can happen that an event channel is being removed from the
system while the event handling loop is active. This can lead to a
race resulting in crashes or WARN() splats when trying to access the
irq_info structure related to the event channel.
Fix this problem by using a rwlock taken as reader in the event
handling loop and as writer when deallocating the irq_info structure.
As the observed problem was a NULL dereference in evtchn_from_irq()
make this function more robust against races by testing the irq_info
pointer to be not NULL before dereferencing it.
And finally make all accesses to evtchn_to_irq[row][col] atomic ones
in order to avoid seeing partial updates of an array element in irq
handling. Note that irq handling can be entered only for event channels
which have been valid before, so any not populated row isn't a problem
in this regard, as rows are only ever added and never removed.
This is XSA-331.

From 6acf1ba7596a051d6ff4092d22bf9c4ce210d9f5 Mon Sep 17 00:00:00 2001
From: Vidya Sagar <vidyas@nvidia.com>
Date: Sat, 11 Jan 2020 00:44:59 +0530
Subject: [PATCH 2/2] arm64: tegra: Re-order PCIe aperture mappings to support
ACPI boot
Re-order Tegra194's PCIe aperture mappings to have IO window moved to
64-bit aperture and have the entire 32-bit aperture used for accessing
the configuration space. This makes it to use the entire 32MB of the 32-bit
aperture for ECAM purpose while booting through ACPI.

From: Thadeu Lima de Souza Cascardo <cascardo@canonical.com>
When dccps_hc_tx_ccid is freed, ccid timers may still trigger. The reason
del_timer_sync can't be used is because this relies on keeping a reference
to struct sock. But as we keep a pointer to dccps_hc_tx_ccid and free that
during disconnect, the timer should really belong to struct dccp_sock.
This addresses CVE-2020-16119.

This reverts commit 2677d20677314101293e6da0094ede7b5526d2b1.
This fixes an issue that after disconnect, dccps_hc_tx_ccid will still be
kept, allowing the socket to be reused as a listener socket, and the cloned
socket will free its dccps_hc_tx_ccid, leading to a later use after free,
when the listener socket is closed.
This addresses CVE-2020-16119.
Fixes: 2677d2067731 (dccp: don't free ccid2_hc_tx_sock struct in dccp_disconnect())

Subject: [PATCH v3 1/3] brcmfmac: increase F2 watermark for BCM4329

This patch fixes SDHCI CRC errors during of RX throughput testing on
BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the
checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark
value is borrowed from downstream BCMDHD driver and it's matching to the
value that is already used for the BCM4339 chip, hence let's re-use it
for BCM4329.
