Fix is incl. in the jammy kernel since: Ubuntu-5.15.0-120.130
and we are currently at: 5.15.0.125.124 (jammy-updates)
and the fix is incl. in the noble kernel since: Ubuntu-6.8.0-48.48
and we are currently at: 6.8.0-48.48 (noble-updates).
Hence I'm updating the affects jammy and noble entries to Fix Released,
and with that also the project entry to Fix Released, hence closing it all.

Bug description:
Description: KVM: s390: unhandled guest LPSWEY instruction
Symptom: guest kernel oops on LPSWEY instruction
Problem: in rare cases like machine check injection with
PSW disabled, all load PSW instructions are
intercepted. LPSW and LPSWE are handled by KVM but
not the new LPSWEY
Solution: Provide an LPSWEY handler in KVM.
Reproduction: hotplug a device while a CPU is disabled for machine
checks, e.g. during early boot
