Hi,

here's a small set of fixes which materialized from me staring at the
AMD side of the loader code in recent times.

Comments and suggestions are always appreciated.

Thx.

[ TODO for self: Add patches 1 and 2 in patch 3's stable field as
   prerequisites for backporting. ]

  x86/microcode/amd: Remove load_microcode_amd()'s bsp parameter
  x86/microcode/AMD: Add a @cpu parameter to the reloading functions
