The MIO Instruktionen patches and their commit IDs are already in eoan:
8e4708b3f8d9 s390/pci: add mio_enabled attribute
9964f396f1d0 s390: fix setting of mio addressing control
6ae3483d4116 s390/pci: correctly handle MIO opt-out
c7ff0e918a7c s390/pci: deal with devices that have no support for MIO instructions dcd33b23c9f3 s390/pci: fix assignment of bus resources
1354b38b3ddf s390/pci: fix struct definition for set PCI function.
Hence the fix for the directed interrupts MSI msg data:
cf2c4a3f35b7 s390/pci: fix MSI message data
is the only one that's missing in eoan.
