This patch appears to be causing breakage on a number of 32 bit arm
platforms, including qemu's virt-2.11,gic-version=3. Affected platforms
die on boot with no output, a bisect with qemu points at this commit and
those for physical platforms appear to be converging on the same place.
Can you share how this can be reproduced with qemu?

Turns out it's actually producing output on qemu:

- I'd only been sampling the logs for the physical platforms, none of
which had shown anything.
Hangs that early need "earlycon", which the qemu boot above does have.
