[ Upstream commit 690afc165b ]
Support for moving IPv4 GRE tunnels between namespaces was added in
commit b57708add3 ("gre: add x-netns support"). The respective change
for IPv6 tunnels, commit 22f08069e8 ("ip6gre: add x-netns support")
did not drop NETIF_F_NETNS_LOCAL flag so moving them from one netns to
another is still denied in IPv6 case. Drop NETIF_F_NETNS_LOCAL flag from
ip6gre tunnels to allow moving ip6gre tunnel endpoints between network
namespaces.

[ Upstream commit 3546d8f1bb =
The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
cxgb_extension_ioctl().
One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
to read memory directly out of the adapter and return it to userspace.
It's not entirely clear what the contents of the adapter memory
contains, but the assumption is that it shouldn't be accessible to all
users.
So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
the is_offload() check, which matches two of the other subcommands in
the same function which also check for is_offload() and CAP_NET_ADMIN.
Found by Ilja by code inspection, not tested as I don't have the
required hardware.

[ Upstream commit 62ebaeaede ]
After LRO/GRO is applied, SRv6 encapsulated packets have
SKB_GSO_IPXIP6 feature flag, and this flag must be removed right after
decapulation procedure.
Currently, SKB_GSO_IPXIP6 flag is not removed on End.D* actions, which
creates inconsistent packet state, that is, a normal TCP/IP packets
have the SKB_GSO_IPXIP6 flag. This behavior can cause unexpected
fallback to GSO on routing to netdevices that do not support
SKB_GSO_IPXIP6. For example, on inter-VRF forwarding, decapsulated
packets separated into small packets by GSO because VRF devices do not
support TSO for packets with SKB_GSO_IPXIP6 flag, and this degrades
forwarding performance.
This patch removes encapsulation related GSO flags from the skb right
after the End.D* action is applied.

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.
To fix this issue, deallocate 'vcc' before the error code is returned.

Commit 287422a95f ("drm/rockchip: Round up _before_ giving to the clock framework")
changed what rate clk_round_rate() is called with, an additional 999 Hz
added to the requsted mode clock. This has caused a regression on RK3328
and presumably also on RK3228 because the inno-hdmi-phy clock requires an
exact match of the requested rate in the pre pll config table.
When an exact match is not found the parent clock rate (24MHz) is returned
to the clk_round_rate() caller. This cause wrong pixel clock to be used and
result in no-signal when configuring a mode on RK3328.
Fix this by rounding the rate down to closest 1000 Hz in round_rate func,
this allows an exact match to be found in pre pll config table.

[ Upstream commit f9e50b02a9 ]
The cio layer's intparm logic does not align itself well with how qeth
manages cmd IOs. When an active IO gets terminated via halt/clear, the
corresponding IRQ's intparm does not reflect the cmd buffer but rather
the intparm that was passed to ccw_device_halt() / ccw_device_clear().
This behaviour was recently clarified in
commit b91d9e67e5 ("s390/cio: fix intparm documentation").
As a result, qeth_irq() currently doesn't cancel a cmd that was
terminated via halt/clear. This primarily causes us to leak
card->read_cmd after the qeth device is removed, since our IO path still
holds a refcount for this cmd.
For qeth this means that we need to keep track of which IO is pending on
a device ('active_cmd'), and use this as the intparm when calling
halt/clear. Otherwise qeth_irq() can't match the subsequent IRQ to its
cmd buffer.
Since we now keep track of the _expected_ intparm, we can also detect
any mismatch; this would constitute a bug somewhere in the lower layers.
In this case cancel the active cmd - we effectively "lost" the IRQ and
should not expect any further notification for this IO.

without calling bio_endio(), for example, blk_rq_unprep_clone() is

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

lead to an uninitialized variable bug in the caller. This seems like a
reasonable warning and it doesn't hurt to silence it at least.

[ Upstream commit 50cc7e3e4f ]
Since 5.4-rc1, pwm_apply_state calls ->get_state after ->apply
if available, and this revealed an issue with integer precision
when calculating duty_cycle and period for the currently set
state in ->get_state callback.
This issue manifested in broken backlight on several Allwinner
based devices.
Previously this worked, because ->apply updated the passed state
directly.

[ Upstream commit cb0701acfa ]
When commit 68bdb67732 ("ACPI: add support for ACPI reconfiguration
notifiers") introduced reconfiguration notifiers, it missed the point
that the ACPI table, which might be loaded and then unloaded via
ConfigFS, could contain devices that were not enumerated by their
parents.
In such cases, the stale platform device is dangling in the system
while the rest of the devices from the same table are already gone.
Introduce acpi_platform_device_remove_notify() notifier that, in
similar way to I²C or SPI buses, unregisters the platform devices
on table removal event.
