#     powerpc/64: Fix booting large kernels with STRICT_KERNEL_RWX
#     
#     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.
#     
#     Fixes: 1e0fc9d1eb2b ("powerpc/Kconfig: Enable STRICT_KERNEL_RWX for some configs")
