Comment 14 for bug 1830243

Yeah lets focus on 2497b4a3 "s390-bios: Skip bootmap signature entries" here then.
If ever "IPLing from a dasd attached via vfio-ccw" is wanted that would be an extra bug/discussion.
Thanks Christian B. for pointing to the core change of this bug!

That way it applies as-is to 3.1, with very slight noise to 2.11 and even 2.5.
Started test builds in [1] as a PPA to evaluate.

Who has s390x test kernels with secure boot enabled available to give this a try?
Marking the bug tasks incomplete until that has been verified.

For formal review MPs are up [2][3][4] as well.

P.S. Cosmic will be EOL until this reaches the SRU queues. Not preparing that.
