Comment 5 for bug 2050019

Well, I was not able to easily cherry-pick these t commits.
I got merge conflicts due to several debug lines.

After some investigations (using git blame) I found that the commits:
0ccac4529540 s390/pkey: harmonize pkey s390 debug feature calls
6d749b4e0208 s390/pkey: introduce dynamic debugging for pkey
seem to be needed - then even some more.
I finally found that adding the following set of commits (that I've found as block earlier in git log):
88e4c0da9b08 s390/zcrypt: harmonize debug feature calls and defines
08b2c3706de2 s390/zcrypt: introduce dynamic debugging for AP and zcrypt code
0ccac4529540 s390/pkey: harmonize pkey s390 debug feature calls
6d749b4e0208 s390/pkey: introduce dynamic debugging for pkey
6a2892d09df5 s390/ap: add debug possibility for AP messages
b69b65f51148 s390/zcrypt: add debug possibility for CCA and EP11 messages
helped me to apply the initial commits.

And with that I was also able to build a test kernel in PPA:

Please can you confirm that it's reasonable to go with these (in total now) 13 commits instead?
