- Use a bit more care when moving I/O APIC interrupts between CPUs.  Mask
  the interrupt followed by a brief delay if it is not currently masked
  before moving the interrupt.
- Move the icu_lock out of ioapic_program_intpin() and into callers.  This
  closes a race where ioapic_program_intpin() could use a stale value of
  the masked state to compute the masked bit in the register.
