      xen: support CONFIG_MAXSMP · 900cba88
      Andrew Jones 提交于
      The MAXSMP config option requires CPUMASK_OFFSTACK, which in turn
      requires we init the memory for the maps while we bring up the cpus.
      MAXSMP also increases NR_CPUS to 4096. This increase in size exposed an
      issue in the argument construction for multicalls from
      xen_flush_tlb_others. The args should only need space for the actual
      number of cpus.
      
      Also in 2.6.39 it exposes a bootup problem.
