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. Signed-off-by:

Balloon driver uses several PV-only concepts (xen_start_info, xen_extra_mem,..) and it seems the simpliest solution to make HVM-only build happy is to decorate these parts with #ifdefs. Signed-off-by:

__pfn_to_mfn() is only used from PV code (mmu_pv.c, p2m.c) and from page.h where all functions calling it check for xen_feature(XENFEAT_auto_translated_physmap) first so we can replace it with any stub to make build happy. set_foreign_p2m_mapping()/clear_foreign_p2m_mapping() are used from grant-table.c but only if !xen_feature(XENFEAT_auto_translated_physmap).

Pull locking updates from Ingo Molnar: "The main changes in this cycle were: - a big round of FUTEX_UNLOCK_PI improvements, fixes, cleanups and general restructuring - lockdep updates such as new checks for lock_downgrade() - introduce the new atomic_try_cmpxchg() locking API and use it to optimize refcount code generation - ... plus misc fixes, updates and cleanups" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (38 commits) MAINTAINERS: Add FUTEX SUBSYSTEM futex: Clarify mark_wake_futex memory barrier usage futex: Fix small (and harmless looking) inconsistencies futex: Avoid freeing an active timer rtmutex: Plug preempt count leak in rt_mutex_futex_unlock() rtmutex: Fix more prio comparisons rtmutex: Fix PI chain order integrity sched,tracing: Update trace_sched_pi_setprio() sched/rtmutex: Refactor rt_mutex_setprio() rtmutex: Clean up sched/deadline/rtmutex: Dont miss the dl_runtime/dl_period update sched/rtmutex/deadline: Fix a PI crash for deadline tasks rtmutex: Deboost before waking up the top waiter locking/ww-mutex: Limit stress test to 2 seconds locking/atomic: Fix atomic_try_cmpxchg() semantics lockdep: Fix per-cpu static objects futex: Drop hb->lock before enqueueing on the rtmutex futex: Futex_unlock_pi() determinism futex: Rework futex_lock_pi() to use rt_mutex_*_proxy_lock() futex,rt_mutex: Restructure rt_mutex_finish_proxy_lock() ...
