+Generally patches for a stable release/branch must first be included in the
+master QEMU branch, and from there the stable branch's maintainer will
+cherry-pick/backport the patch. However, occasionally there is a need to

+cherry-picked and has been reworked/backported specifically for a stable
+branch, or a fix that's only necessary in the context of a particular stable
