    x86, microcode, AMD: Fix early microcode loading · 84516098
    Torsten Kaiser authored
    load_microcode_amd() (and the helper it is using) should not have an
    cpu parameter. The microcode loading does not depend on the CPU wrt the
    patches loaded since they will end up in a global list for all CPUs
    anyway.
    
    The change from cpu to x86family in load_microcode_amd()
    now allows to drop the code messing with cpu_data(cpu) from
    collect_cpu_info_amd_early(), which is wrong anyway because at that
    point the per-cpu cpu_info is not yet setup (These values would later be
    overwritten by smp_store_boot_cpu_info() / smp_store_cpu_info()).
    
    Fold the rest of collect_cpu_info_amd_early() into load_ucode_amd_ap(),
    because its only used at one place and without the cpuinfo_x86 accesses
    it was not much left.
