According to the affected binutils versions and the communication with
IBM it's sufficient to get this fixed in Bionic.

Bug description:
  Please backport the following bugfix into Ubuntu LTS:
  https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e6213e09ed0e

  Some relevant historic links:

  In s390 kernel context, this bug manifests itself as random errors and
  infinite loops, so it's fairly severe.

  These are the current versions of binutils:
  Package binutils

      xenial (16.04LTS) (devel): GNU assembler, linker and binary utilities
      2.26.1-1ubuntu1~16.04.8 [security]: amd64 i386
      2.26-8ubuntu2 [ports]: arm64 armhf powerpc ppc64el s390x

      bionic (18.04LTS) (devel): GNU assembler, linker and binary utilities
      2.30-21ubuntu1~18.04.4 [security]: amd64 i386
      2.30-15ubuntu1 [ports]: arm64 armhf ppc64el s390x
      bionic-updates (devel): GNU assembler, linker and binary utilities

      focal (20.04LTS) (devel): GNU assembler, linker and binary utilities
      2.34-6ubuntu1: amd64 arm64 armhf i386 ppc64el s390x
      groovy (devel): GNU assembler, linker and binary utilities
      2.35.1-1ubuntu1: amd64 arm64 armhf i386 ppc64el s390x

  The patch applies fine to 2.26 and 2.30 (except for tests, but we
  don't need them). We don't need it on 2.32+.
