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.

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.

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.

This is not necessary on our systems and according to the documentation
will reduce code size of the allocator which will result in better
performance.

This is a new type of metric to find out what resource is currently a
bottleneck for the whole system. We might use this for graphs.

This change is required to make the system respond faster to any
realtime events (sending or receiving data packets).
It will wake up at least one core 1000 times a second which will result
in finer timer granularity and make scheduling smoother. HTB for
example sends large packet bursts on each timer even to keep up data
rates which is not helpful for most applications.
The change might increase resource consumption and overhead slightly on
some systems, but since we are running in an idle-dyntick configuration,
we should not keep awake any cores that have not been awake before.

we have no supported armv5tel board left so we can switch to the higher
arch. This now can use the vpu (still in softfp calling convention to
not break existing installations.)
this fix many compile problems, also boost is now working again.
