No, I assume it's because the function calls from the .init section are
located too far away from the other code. Reason is probably because
huge pages are selected and thus I tried to pack the init section so that
it can get discarded after bootup.
I'll look into it now...

I think the only way to fix this in a clean way is to
enable CONFIG_MLONGCALLS, which lets gcc use -mlong-calls compiler
option and thus creates far calls.
The problem is, that those calls are far more less performant, which one
usually don't want to use in production kernels.
In addition, typical Linux distribution kernels have most
drivers built as modules and as such don't need this option.
One way I can think of to work around that issue is, that if Kconfig detects
that we build a test robot kernel, simply to enable this option.
That way the test robot still builds everything.
Is there a way to detect at compile/build time if the kernel
is configured/built by the test robot? Is there maybe some config option
or environment variable set which could be used?
Maybe someone has another/better idea as well?

That's currently the only way to work around the R_PARISC_PCREL22F relocation error. We need
long branch stub support in 64-bit linker.
