Currently vcpu_id is used as an index into vcpus array and as apic id
on x86.  This is incorrect since apic ids not have to be continuous
(they can also encode cpu hierarchy information) and may have values
bigger then vcpu array in case of x2apic. This series removes use of
vcpu_id as vcpus array index. Each architecture may use it how it sees
fit. x86 uses it as apic id.

v2:
  remove online_vcpus from ia64 in patch 3/4
  introduce KVM_APIC_ARCHITECTURE config option

Gleb Natapov (4):
  Introduce kvm_vcpu_is_bsp() function.
  Use pointer to vcpu instead of vcpu_id in timer code.
  Break dependency between vcpu index in vcpus array and vcpu_id.
  Use macro to iterate over vcpus.
