Quentin Casasnovas f84598bd7c x86/microcode/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.
