- 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.
