  x86: Remove asm/apicnum.h
  x86: apic: Do not use stacked physid_mask_t
  x86, apic: Get rid of apicid_to_cpu_present assign on 64-bit
  x86, ioapic: Use snrpintf while set names for IO-APIC resourses
  x86, apic: Use PAGE_SIZE instead of numbers
  x86: Remove local_irq_enable()/local_irq_disable() in fixup_irqs()
  x86: Use EOI register in io-apic on intel platforms
  x86: Force irq complete move during cpu offline
  x86: Remove move_cleanup_count from irq_cfg
