Name	Describe
__ioapic_write_entry	When we write a new IO APIC routing entry, we need to write the high* word first! If the mask bit in the low word is clear, we will enable* the interrupt, and we need to make sure the entry is fully populated* before that happens.
ioapic_mask_entry	When we mask an IO APIC routing entry, we need to write the low* word first, in order to set the mask bit before we change the* high bits!
