We worked around that problem in the past by marking it __ref, see

Since de78a9c "powerpc: Add a framework for Kernel Userspace Access
Protection", user access helpers call user_{read|write}_access_{begin|end}
when user space access is allowed.
890274c "powerpc/64s: Implement KUAP for Radix MMU" made the mentioned
helpers program a AMR special register to allow
The kernel call these functions on cpu online and hence they should
not be marked __init.

radix")
