Merge tag 'amd_ucode_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp into x86/urgent

Pull AMD microcode fixes from Borislav Petkov:

 " Those are basically two fixes which correct the AMD early ucode loader
   from accessing cpu_data too early, i.e. before smp_store_cpu_info()
   has copied the boot_cpu_data ontop and overwritten an already empty
   structure (which we shouldn't access that early in the first place
   anyway).

   The second patch is kinda largish for that late in the game but it
   shouldn't be problematic because we're simply switching from using
   cpu_data to use the CPU family number directly and thus again, not use
   uninitialized cpu_data structure. "
