With STRICT_KERNEL_RWX enabled anything marked __init is placed at a 16M
boundary. This is necessary so that it can be repurposed later with
different permissions. However, in kernels with text larger than 16M,
this pushes early_setup past 32M, incapable of being reached by the
branch instruction.
Fix this by setting the CTR and branching there instead.
