From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Introduce an override for the arch_[teardown|setup]_msi_irqs that can be utilized to fallback to the default arch_* code. If a platform wants to utilize the code paths defined in driver/pci/msi.c it has to define HAVE_DEFAULT_MSI_TEARDOWN_IRQS or HAVE_DEFAULT_MSI_SETUP_IRQS. Otherwise the old mechanism of over-ridding the arch_* works fine.
