In such cases current logic fails to handle it and throws error "Invalid bus_irq %u for legacy override". This patch handles the above mentioned case. While at it, also modify function mp_override_legacy_irq() to use the newly introduced function mp_register_ioapic_irq(). This series is rebased on 'master' branch of https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git Changes since v2: Addressed the review comments by Thomas Gleixner to fix the broken Signed-off-by chain, code clean up and some comments removal. Changes since v1: Patch is split into 2, separating actual fix and code cleanup as suggested by Rafael.
