Compiling the kernel has automatically introduced
CONFIG_INIT_STACK_ALL_ZERO=y and removed GCC's structleak plugin (not to
be confused with its stackleak counterpart). However, according to
related documentation, this neither introduces a security nor
performance disadvantage.

This removes support for building IPFire for 32 bit ARM architectures.
This has been decided in August 2022 with six months notice as there are
not very many users and hardware is generally not available any more.

These two patches are needed to support SFP's on NXP DPAA2 platforms
(e.g Traverse Ten64).
The deadlock issue patch was submitted upstream a while ago and
rejected, however I am not aware of any better solutions at present.
The 10G mode additions are part of mainline since 5.16.
These two .patches were sourced from our patchset over here:

Please refer to https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15.57
for the changelog of this version. Since it introduces
architecture-dependent rootfile changes due to CPU side-channel
mitigations, changes to ARM rootfiles have been omitted due to the lack
of hardware.
Supposed hardening changes will be submitted separately.

This patch, which has been merged into the mainline Linux kernel, but
not yet backported to the 5.15.x tree, precisely addresses our
situation: IPFire does not use systemd, but CONFIG_DEVTMPFS_MOUNT.
The only explanation I have for bug #12889 arising _now_ is that some
component (dracut, maybe) changed its behaviour regarding remounting of
already mounted special file systems. As current dracut won't (re)mount
any file system already found to be mounted, this means that the mount
options decided by the kernel remained untouched for /dev, hence being
weak in terms of options hardening possible.
As CONFIG_DEVTMPFS_SAFE would not show up in "make menuconfig", changes
to kernel configurations have been simulated.
Fixes: #12889

in kernel 5.15.32 the driver for ATH9K wlan cards is unstable.
This is one of the most used cards so we need this update before
releasing core167 final.

flashrom needs access to /dev/io ports for flashing firmware, a
functionality we cannot cease to support. Therefore, LSM constraints are
disabled for ioport.c, hopefully permitting us to keep it enabled.
