Linus, what -next are you testing on? I am using next-20200916.
next-20200916 completely broken on ARM and ARM64. Please check
next-20200915 + the mentioned fix or just check
https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=irq/ipi-as-irq
Ah thanks! Any idea what is causing the other failure on next-20200916?

Yes we have noticed that now everything fails next-20200916 so not just
this issue.

The issue is caused by commit c999bd436fe9 ("mm/cma: make number of CMA
areas dynamic, remove CONFIG_CMA_AREAS")

There is a workaround here[1] for arm64, but I doubt that's the end of
it (32bit is still dead).
