Bug description:
  [execution in the early microcode loader x86/intel] Guard against
  stack overflow in the loader mc_saved_tmp is a static array allocated
  on the stack, we need to make sure mc_saved_count stays within its
  bounds, otherwise we're overflowing the stack in _save_mc(). A
  specially crafted microcode header could lead to a kernel crash or
  potentially kernel execution.

  Break-Fix: ec400ddeff200b068ddc6c70f7321f49ecf32ed5
