This improves compatibility for guests w.r.t. live-migration, or live
snapshot rollback, to hosts with less (FPU) xfeatures supported, as
long as the set of features that was actually exposed to the guest is
still supported.
This improves on the ad856280ddea ("x86/kvm/fpu: Limit guest
user_xfeatures to supported bits of XCR0") bug fix.

this exposes the FLUSHBYASID CPU flag to nested VMs when running on an
AMD CPU. also reverts a made up check that would advertise
FLUSHBYASID as not supported. this enable certain modern hypervisors
such as VMWare ESXi 7 and Workstation 17 to run nested VMs properly
again.

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`

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.

Avoids regressions where some code falsely think they cannot use some
CPU features like AVX1, e.g., ZFS.

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.

The mailing list thread [0] (found by Friedrich, many thanks!) leading
up to this patch sounds very familiar to issues users reported in the
community forum [1] and enterprise support channel, where a VM would
be stuck for no discernable reason with all vCPU threads spinning.
