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.
