Boris Ostrovsky ce2612b670 x86/smp: Factor out parts of native_smp_prepare_cpus() ... Commit 66558b730f ("sched: Add cluster scheduler level for x86") introduced cpu_l2c_shared_map mask which is expected to be initialized by smp_op.smp_prepare_cpus(). That commit only updated native_smp_prepare_cpus() version but not xen_pv_smp_prepare_cpus(). As result Xen PV guests crash in set_cpu_sibling_map(). While the new mask can be allocated in xen_pv_smp_prepare_cpus() one can see that both versions of smp_prepare_cpus ops share a number of common operations that can be factored out. So do that instead.
