Thomas Gleixner bc07844a33 x86: Distangle ioapic and i8259 ... The proposed Moorestown support patches use an extra feature flag mechanism to make the ioapic work w/o an i8259. There is a much simpler solution. Most i8259 specific functions are already called dependend on the irq number less than NR_IRQS_LEGACY. Replacing that constant by a read_mostly variable which can be set to 0 by the platform setup code allows us to achieve the same without any special feature flags. That trivial change allows us to proceed with MRST w/o doing a full blown overhaul of the ioapic code which would delay MRST unduly.
