Subject: [PATCH v2 21/21] x86/xen: rename some PV-only functions in smp_pv.c
After code split between PV and HVM some functions in xen_smp_ops have
xen_pv_ prefix and some only xen_ which makes them look like they're
common for both PV and HVM while they're not. Rename all the rest to
have xen_pv_ prefix.

- This patch is rather a matter of taste and it makes code archeology
slightly harder, we may consider dropping it from the series.
