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

* 'cpus4096-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  [IA64] fix typo in cpumask_of_pcibus()
  x86: fix x86_32 builds for summit and es7000 arch's
  cpumask: use work_on_cpu in acpi-cpufreq.c for read_measured_perf_ctrs
  cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write
  cpumask: use cpumask_var_t in acpi-cpufreq.c
  cpumask: use work_on_cpu in acpi/cstate.c
  cpumask: convert struct cpufreq_policy to cpumask_var_t
  cpumask: replace CPUMASK_ALLOC etc with cpumask_var_t
  x86: cleanup remaining cpumask_t ops in smpboot code
  cpumask: update pci_bus_show_cpuaffinity to use new cpumask API
  cpumask: update local_cpus_show to use new cpumask API
  ia64: cpumask fix for is_affinity_mask_valid()
