This is another __visible candidate.

This one is called by the core kernel. Please instead lift the
extern in init/main.c to include/linux/irq.h or some other suitable
header insted of working around the issue in arch code.

Another generic issue, Ben Dooks has started looking into it already.

And another one that needs to be solved globally and not worked around
in the architecture.

Again, this needs to go into a common header, no arch code.

One more __visible candidate.
