Commit: a18a0f68 ("x86, microcode: Don't initialize microcode code on paravirt") added a paravirt test in microcode_init(), primarily to avoid making mc_bp_resume()->load_ucode_ap()->check_loader_disabled_ap() calls because on 32-bit kernels this callchain ends up using __pa_nodebug() macro which is invalid for Xen PV guests. A subsequent commit: fbae4ba8 ("x86, microcode: Reload microcode on resume") eliminated this callchain thus making a18a0f68 unnecessary.
