[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
