1fad035a1f Kernel: Mitigate Straight-Line-Speculation on x86_64 
See https://lwn.net/Articles/877845/ for the rationale behind this. The
feature is currently only available on the x86_64 platform.

883e29630c Kernel: Disable support for RPC dprintk debugging 
This is solely needed for debugging of NFS issues. Due to the attack
surface it introduces, grsecurity recommends to disable it; as we do not
have a strict necessity for this feature, it is best to follow that
recommendation for security reasons.

9b28e9d02b Kernel: Enable YAMA support 
See https://www.kernel.org/doc/html/latest/admin-guide/LSM/Yama.html for
the upstream rationale. Enabling YAMA gives us the benefit of additional
hardening options available, without any obvious downsides.

9fa01e4276 kernel: update to 5.15.35 
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.

250f6efc38 kernel: Do not enforce "integrity" mode of LSM 
LSM was found to render firmware flashing unusable, and patching out LSM
functionality for all features needed (such as /dev/io, direct memory
access and probably raw PCI access for older cards), this would
effectively render much of LSM's functionality useless as well.

For the time being, we do ship LSM, but do not enforce any protection
mode. Users hence can run it in "integrity" or even "confidentiality"
mode by custom commands; hopefully, we will be able to revert this
change at a future point.

11925d6f9f Kernel: Enable SVA support for both Intel and AMD CPUs

makes sense to provide Qemu with the ability of taking advantage of
IOMMU support for safer virtuall memory allocation, if available.

5c1a1094ed kernel: Add a basic configuration for riscv64 
This kernel configuration is a copy of our kernel configuration for
x86_64 on which I ran "make olddefconfig" which will set any unknown
values to their defaults.

This exists so that we have some kernel (which I did not try to boot) to
complete the build process.

6cf219c427 Drop support for i586 
This patch removes support for i586 according to the decision being
taken over a year ago.

It removes the architecture from the build system and removes all
required hacks and other quirks that have been necessary before.

There is no need to ship any changed files to the remaining
architectures as the removed code branches have not been used.
