Comment 14 for bug 1953338

They might be backported to plain 4.2, but they do not apply cleanly to 1:4.2-3ubuntu6.19.

0001 & 0002:
The patch directly from upstream git applies, but your backport does not - so I just used cherry picks

0003:
Neither your backprt nor a cherry pick worked as-is.

Here things start to be rather different and instead of bad-backporting - and potentially even missing the point what the target was - I think i use this opportunity to ask.

1. What was this meant for - Focal?
2. For a backport to exactly what Focal has right see below:

I guess you do not want to think about Debian packaging too much, you can do so via (there are many ways, but this is at least one):

git clone -b ubuntu/focal-devel https://git.launchpad.net/ubuntu/+source/qemu
cd qemu
QUILT_PATCHES="debian/patches" quilt push --fuzz=0 -a
git add .
git commit -m "Current Focal base"

This will be 4.2 + all patches in Ubuntu for you to work with.
