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.

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

   uninitialized cpu_data structure. "
