Merge tag 'smp-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull core SMP updates from Thomas Gleixner:
 "A small set of SMP core code changes:

   - Rework the smp function call core code to avoid the allocation of
     an additional cpumask

   - Remove the not longer required GFP argument from on_each_cpu_cond()
     and on_each_cpu_cond_mask() and fixup the callers"

* tag 'smp-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  smp: Remove allocation mask from on_each_cpu_cond.*()
  smp: Add a smp_cond_func_t argument to smp_call_function_many()
  smp: Use smp_cond_func_t as type for the conditional function
