  qemu (1:8.2.2+ds-0ubuntu1.7) noble; urgency=medium

  * d/p/u/lp2049698/*: Add full boot order support on s390x (LP: #2049698)
  * Cherry-pick prerequisite for above backport (to avoid FTBFS):
    - d/p/u/lp2049698/0-hw-s390x-sclp.c-include-s390-virtio-ccw.h-to-make.patch
  * d/qemu-system-data.links: symlink s390-netboot.img -> s390-ccw.img for
    backwards compatibility, as the code is now combined.

  [ Michael Tokarev ]
  * d/rules: run ./configure in arch-indep build and build some roms from there.
    After adding just a few more build-deps to common Build-Depends,
    it is now possible to run ./configure in arch-indep step too.
    Run ./configure, and switch s390-ccw and vof.bin builds from
    ad-hoc instructions to using the regular qemu makefiles.
    Move python3-venv dependency from Build-Depend-Arch to Build-Depend
    so that ./configure can be run.
    [cherry-pick https://salsa.debian.org/qemu-team/qemu/-/commit/5b5a97b]

  * Fix qemu-aarch64-static segfaults running ldconfig.real (LP: #2072564)
