829cc60a28 kernel: backport flow_dissect support for tag_brcm
This change helps BCM4908 SoC. It was capable of 940 Mb/s masq NAT while
using iperf but users reported lower & unstable speeds for HTTP based
tests.

For LibreSpeed tests this bumps NAT speed from ~930 Mb/s to ~990 Mb/s
(not that this value seems real but speed bump definitely is).

c6ddf8d502 kernel: bump 5.4 to 5.4.179
Many changes were done in drivers/pinctrl/bcm/pinctrl-bcm2835.c between
5.4.171 and 5.4.179.
The following 3 patches do not apply any more:
* target/linux/bcm27xx/patches-5.4/950-0316-pinctrl-bcm2835-Add-support-for-BCM2711-pull-up-func.patch
  This was already integrated in kernel v5.4-rc1, it was never needed.

* target/linux/bcm27xx/patches-5.4/950-0328-Revert-pinctrl-bcm2835-Pass-irqchip-when-adding-gpio.patch
* target/linux/bcm27xx/patches-5.4/950-0362-pinctrl-bcm2835-Change-init-order-for-gpio-hogs.patch
I think these were done to fix the problem which was really fixed in
commit 75278f1aff5e ("pinctrl: bcm2835: Change init order for gpio
hogs") from v5.4.175

c37a9e506c kernel: backport switchdev fix for bridge in bridge configurations
This patch fixes the forwarding behavior of bridge in bridge
configurations with DSA.

Without it, the configuration of the upper bridge might overwrite
settings of the lower bridge. For example, a vlan-aware bridge
with DSA interfaces in it might be offloaded to the DSA hardware. If the
bridge interface itself gets slave of a different bridge without vlan
filtering, the vlan filtering setting of the lower bridge is overwritten
by the upper bridge, which results in an incorrect hardware
configuration.

This was backported from kernel 5.7.

ec780bdb92 kernel-5.4: backport latest patches for wireguard
These are the latest patches that just landed upstream for 5.13, will be
backported by Greg into 5.10 (because of stable@), and are now in the
5.4 backport branch of wireguard: https://git.zx2c4.com/wireguard-linux/log/?h=backport-5.4.y

f49d4aebe2 kernel: Activate FORTIFY_SOURCE for MIPS kernel 5.4
CONFIG_FORTIFY_SOURCE=y is already set in the generic kernel
configuration, but it is not working for MIPS on kernel 5.4, support for
MIPS was only added with kernel 5.5, other architectures like aarch64
support FORTIFY_SOURCE already since some time.

This patch adds support for FORTIFY_SOURCE to MIPS with kernel 5.4,
kernel 5.10 already supports this and needs no changes.

This backports one patch from kernel 5.5 and one fix from 5.8 to make
fortify source also work on our kernel 5.4.

The changes are not compatible with the
306-mips_mem_functions_performance.patch patch which was also removed
with kernel 5.10, probably because of the same problems. I think it is
not needed anyway as the compiler should automatically optimize the
calls to memset(), memcpy() and memmove() even when not explicitly
telling the compiler to use the build in variant.

This increases the size of an uncompressed kernel by less than 1 KB.
