acpi_irq_to_vector()

[Matthew Wilcox <willy-8fiUuRrzOP0dnm+yROfE0A@public.gmane.org>]

In the 2.5 ia64 patch, there's a lot of places which look like this:

@@ -251,7 +251,14 @@
        irq = acpi_fadt.sci_int;

 #ifdef CONFIG_IA64
-       irq = gsi_to_vector(irq);
+       int vector;
+
+       vector = acpi_irq_to_vector(irq);
+       if (vector < 0) {
+               printk(KERN_ERR PREFIX "SCI (IRQ%d) not registerd\n", irq);
+               return AE_OK;
+       }
+       irq = vector;
 #endif
        acpi_irq_irq = irq;

ok, we renamed gsi_to_vector to acpi_irq_to_vector(); that's fine.
But we still have that ugly ifdef in there.  Any resistance to defining
acpi_irq_to_vector to simply return its value on non-ia64 platforms?

Then it'd look like:

	irq = acpi_fadt.sci_int;
	vector = acpi_irq_to_vector(irq);
	if (vector < 0) {
		printk(KERN_ERR PREFIX "SCI (IRQ%d) not registered\n", irq);
		return AE_OK;
	}
	acpi_irq_irq = vector;
	acpi_irq_handler = handler;
	acpi_irq_context = context;
	if (request_irq(vector, acpi_irq, SA_SHIRQ, "acpi", acpi_irq)) {
