#     powerpc/64s: Convert some cpu_setup() and cpu_restore() functions to C
#     
#     The only thing keeping the cpu_setup() and cpu_restore() functions used
#     in the cputable entries for Power7, Power8, Power9 and Power10 in
#     assembly was cpu_restore() being called before there was a stack in
#     generic_secondary_smp_init(). Commit ("powerpc/64: Set up a kernel stack
#     for secondaries before cpu_restore()") means that it is now possible to
#     use C.
#     
#     Rewrite the functions in C so they are a little bit easier to read. This
#     is not changing their functionality.
