MAINTAINERS: add S390 MM section (2022-11-17 20:23:30 +0100)
----------------------------------------------------------------
s390 updates for 6.1-rc7
- Fix size of incorrectly increased from four to eight bytes
TOD field of crash dump save area. As result in case of
kdump NT_S390_TODPREG ELF notes section contains correct
value and "detected read beyond size of field" compiler
warning goes away.
- Fix memory leak in cryptographic Adjunct Processors (AP)
module on initialization failure path.
- Add Gerald Schaefer <gerald.schaefer@...ux.ibm.com> and
Alexander Gordeev <agordeev@...ux.ibm.com> as S390 memory
management maintainers. Also rename the S390 section to
S390 ARCHITECTURE to be a bit more precise.
