#     powerpc/64: Remove unused generic_secondary_thread_init()
#     
#     The last caller was removed in 2014 in commit fb5a515704d7 ("powerpc:
#     Remove platforms/wsp and associated pieces").
#     
#     As Jordan noticed even though there are no callers, the code above in
#     fsl_secondary_thread_init() falls through into
#     generic_secondary_thread_init(). So we can remove the _GLOBAL but not
#     the body of the function.
#     
#     However because fsl_secondary_thread_init() is inside #ifdef
#     CONFIG_PPC_BOOK3E, we can never reach the body of
#     generic_secondary_thread_init() unless CONFIG_PPC_BOOK3E is enabled,
#     so we can wrap the whole thing in a single #ifdef.
