[PATCH] genirq: i386 irq: Remove the msi assumption that irq == vector
This patch removes the change in behavior of the irq allocation code when CONFIG_PCI_MSI is defined. Removing all instances of the assumption that irq == vector. create_irq is rewritten to first allocate a free irq and then to assign that irq a vector. assign_irq_vector is made static and the AUTO_ASSIGN case which allocates an vector not bound to an irq is removed. The ioapic vector methods are removed, and everything now works with irqs. The definition of NR_IRQS no longer depends on CONFIG_PCI_MSI [akpm@osdl.org: cleanup] Signed-off-by: Eric W.
