If anyone has any objections, please let me know. ------------------ From: Vikas C Sajjan commit 4ee2ec1b122599f7b10c849fa7915cebb37b7edb upstream. The new function mp_register_ioapic_irq() is a subset of the code in mp_override_legacy_irq(). Replace the code duplication by invoking mp_register_ioapic_irq() from mp_override_legacy_irq().
