[PATCH] x86/ioapic: Correctly print IRTE's index field when enabling INTR

Show all headers | View raw

When enabling interrupt remap, IOAPIC's RTE contains interrupt_index
field of IRTE. And this field is composed of index and index2 member of
struct IR_IO_APIC_route_entry. Make io_apic_print_entries() correctly
print interrupt index field.
