    [PATCH] genirq: x86_64 irq: Remove the msi assumption that irq == vector · 04b9267b
    Eric W. Biederman authored
    
    
    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
