[Kernel-packages] [Bug 1904884] Re: [UBUNUT 20.04] s390: dbginfo.sh triggers kernel panic, reading from /sys/kernel/mm/page_idle/bitmap
The commit 92fb1db26eef "mm/page_idle.c: skip offline pages" is upstream with
5.8 (rc-1) (also tagged with next-20200820).
Hence it's in groovy (since Ubuntu-5.8.0-13.14) and in hirsute
(Ubuntu-5.8.0-30.32+21.04.1).
It's not in focal (also not via upstream stable updates).
Hence updating only G and H to Fix Released.

Bug description:
System hangs on dbginfo.sh script execution.
Solution:
Commit 92fb1db26eef ("mm/page_idle.c: skip offline pages")
Included upstream since kernel v5.8, so it is already included in
Ubuntu 20.10, but not in 20.04 and earlier.
Commit 92fb1db26eef ("mm/page_idle.c: skip offline pages") applies cleanly on
ubuntu-focal, but not on ubuntu-bionic.
Adjustment / backport for bionic should be trivial, but it is not IBM
code and therefore the backport will be requested here by Canonical.

Reduced importance from "ship issue" to "high", not a real ship issue, but is
mandatory to be fixed within the service stream
