Commit:
a18a0f6850d4 ("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:
fbae4ba8c4a3 ("x86, microcode: Reload microcode on resume")
eliminated this callchain thus making a18a0f6850d4 unnecessary.
