Later commits will cause objtool to warn about static calls being used in
.noinstr sections in order to safely defer instruction patching IPIs
targeted at NOHZ_FULL CPUs.
pv_sched_clock is updated in:
o __init vmware_paravirt_ops_setup()
o __init xen_init_time_common()
o kvm_sched_clock_init() <- __init kvmclock_init()
o hv_setup_sched_clock() <- __init hv_init_tsc_clocksource()
IOW purely init context, and can thus be marked as __ro_after_init.
