Known issues

Please list all patch series or bugs which need to be fixed for the release here. That way I can be sure I don't miss any when I'm rolling release candidates.

Not fixed yet

• microblaze s3adsp1800 stuck while booting (https://lists.gnu.org/archive/html/qemu-devel/2020-11/msg02183.html) - not a recent regression, also happens with v5.0 already, thus this should likely not block the release
• pci broken for s390x-on-x86 tcg guests, bisected to 28dc86a07299 ("s390x/pci: use a PCI Group structure") (https://lore.kernel.org/qemu-devel/20201117124349.2e1e2fe3.cohuck@redhat.com/)
