  viridian: introduce a per-cpu hypercall_vpmask and accessor
    functions...
  viridian: use hypercall_vpmask in hvcall_ipi()
  viridian: use softirq batching in hvcall_ipi()
  xen/include: import sizeof_field() macro from Linux stddef.h
  viridian: add ExProcessorMasks variants of the flush hypercalls
  viridian: add ExProcessorMasks variant of the IPI hypercall
  viridian: log initial invocation of each type of hypercall
