cherry-pick scheduler fix to avoid temporary VM freezes on NUMA hosts
Users have been reporting [1] that VMs occasionally become
unresponsive with high CPU usage for some time (varying between ~1 and
more than 60 seconds). After that time, the guests come back and
continue running. Windows VMs seem most affected (not responding to
pings during the hang, RDP sessions time out), but we also got reports
about Linux VMs (reporting soft lockups). The issue was not present on
host kernel 5.15 and was first reported with kernel 6.2. Users
reported that the issue becomes easier to trigger the more memory is
assigned to the guests. Setting mitigations=off was reported to
alleviate (but not eliminate) the issue. For most users the issue
seems to disappear after (also) disabling KSM [2], but some users
reported freezes even with KSM disabled [3].
It turned out the reports concerned NUMA hosts only, and that the
freezes correlated with runs of the NUMA balancer [4]. Users reported
that disabling the NUMA balancer resolves the issue (even with KSM
enabled).
We put together a Linux VM reproducer, ran a git-bisect on the kernel
to find the commit introducing the issue and asked upstream for help
[5]. As it turned out, an upstream bugreport was recently opened [6]
and a preliminary fix to the KVM TDP MMU was proposed [7]. With that
patch [7] on top of kernel 6.7, the reproducer does not trigger
freezes anymore. As of now, the patch (or its v2 [8]) is not yet
merged in the mainline kernel, and backporting it may be difficult due
to dependencies on other KVM changes [9].
However, the bugreport [6] also prompted an upstream developer to
propose a patch to the kernel scheduler logic that decides whether a
contended spinlock/rwlock should be dropped [10]. Without the patch,
PREEMPT_DYNAMIC kernels (such as ours) would always drop contended
locks. With the patch, the kernel only drops contended locks if the
kernel is currently set to preempt=full. As noted in the commit
message [10], this can (counter-intuitively) improve KVM performance.
Our kernel defaults to preempt=voluntary (according to
/sys/kernel/debug/sched/preempt), so with the patch it does not drop
contended locks anymore, and the reproducer does not trigger freezes
anymore. Hence, backport [10] to our kernel.

update ZFS for backport of Intel AMX errata fix
From the upstream commit [0] that this update pulls in:
> Intel SPR erratum SPR4 says that if you trip into a vmexit while
> doing FPU save/restore, your AMX register state might misbehave...
> and by misbehave, I mean save all zeroes incorrectly, leading to
> explosions if you restore it.
>
> Since we're not using AMX for anything, the simple way to avoid
> this is to just not save/restore those when we do anything, since
> we're killing preemption of any sort across our save/restores.
>
> If we ever decide to use AMX, it's not clear that we have any
> way to mitigate this, on Linux...but I am not an expert.

cherry-pick fix for new amd64 ucode
The latest amd64-microcode package in sid [0] (which probably will
eventually make it to bookworm-security) has a change that requires
the added patch to work properly.
The changelog-entry refers to stable k.o branches only - but a quick
look through the linux-firmware.git log identifies:
`
f2eb058afc57348cde66852272d6bf11da1eef8f` as relevant commit, which
refers (as NOTE in the patch) to:
a32b0f0db3f3 ("x86/microcode/AMD: Load late on both threads too")
which applies cleanly (although I cherry-picked the patch from the
6.1.y stable branch to have the original commit in the commit
message).
quickly tested compiling and booting the result in a VM (however w/o
a fitting CPU (Epyc Genoa or Bergamo) it should cause a change)
reported in our Enterprise Support as potential culprit for one
thread from 128 being reported as offline in `lscpu`

fix thunderbolt ring-interrupt not being masked on suspend
Originally for v6.4-rc7 and now it also got already into some stable
trees, but not yet into a (released) ubuntu tag – so backport it
already.

backport thunderbolt-net fixes
A user of ours reported an issue with p2p thunderbolt-net w.r.t. IPv6
and failure to reestablish the connection after a reboot of a peer
node, in the forum [0] and the relayed it upstream, so lets
cherry-pick those two patches to our 6.2. Especially the IPv6 one
seems straight forward, and the other one makes it actually spec
conform and should only improve things.
