Have you confirmed:
1) whether this actually builds
2) whether this results in one or two arch_vma_name exports
?

Hi Russell,
We did confirm that it can be built successfully in kernel 6.1 and run
well in our system.
It runs well in your system and can be built successfully because you're building
for ARM64, not for ARM...
Actually, we only use this export symbol "arch_vma_name"
from kernel/signal.c in arm64. We also export symbol for arch_vma_name
in arch/arm/kernel/process.c because that, one day in the future, we
are afraid that we also need this function in arm platform.
Thanks.
Regards,
Jim
