Hi,
v1:
https://lore.kernel.org/xen-devel/20251112162219.226075-1-alejandro.garciavallejo@xxxxxxx/
v2:
https://lore.kernel.org/xen-devel/20260112150259.74535-1-alejandro.garciavallejo@xxxxxxx/
v3:
https://lore.kernel.org/xen-devel/20260113122109.62399-1-alejandro.garciavallejo@xxxxxxx/
pipeline (red, but see below):
https://gitlab.com/xen-project/people/agvallejo/xen/-/pipelines/2272127547
Pipeline failures are on ARM builds, so clearly unrelated to this. Also has
an eclair run on allcode that shows no new failures in earlycpio.c.
The only dependency here is patch 2 going in before patch 3. Everything else
can be freely rearranged.
Cheers,
Alejandro
