Merge branch 'cpus4096-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

* 'cpus4096-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  cpu masks: optimize and clean up cpumask_of_cpu()
  cpumask: export cpumask_of_cpu_map
  cpumask: change cpumask_of_cpu_ptr to use new cpumask_of_cpu
  cpumask: put cpumask_of_cpu_map in the initdata section
  cpumask: make cpumask_of_cpu_map generic
