What makes kernel jump here? Can't see this referenced from anywhere?

Sorry, it is just a left-over from a previous version of this patch
(which implemented the single-step-over-iret). This label is not used
anymore. The jump to it was in
swapgs_restore_regs_and_return_to_usermode, after checking the
sev_es_in_nmi flag.
