#     powerpc/64: mark start_here_multiplatform as __ref
#     
#     Otherwise, the following warning is encountered:
#     
#     WARNING: vmlinux.o(.text+0x3dc6): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
#     The function start_here_multiplatform() references
#     the function __init .early_setup().
#     This is often because start_here_multiplatform lacks a __init
#     annotation or the annotation of .early_setup is wrong.
#     
#     Fixes: 56c46bba9bbf ("powerpc/64: Fix booting large kernels with STRICT_KERNEL_RWX")
