Merge tag 'x86-apic-2021-11-01' of git://git./linux/kernel/git/tip/tip

Pull x86/apic update from Thomas Gleixner:
 "A single commit which reduces cache misses in __x2apic_send_IPI_mask()
  significantly by converting x86_cpu_to_logical_apicid() to an array
  instead of using per CPU storage.

  This reduces the cost for a full broadcast on a dual socket system
  with 256 CPUs from 33 down to 11 microseconds"
