    [PATCH] setting irq affinity is broken in ia32 with MSI enabled
    
    Setting irq affinity stops working when MSI is enabled.  With MSI, move_irq
    is empty, so we can't change irq affinity.  It appears a typo in Ashok's
    original commit for this issue.  X86_64 actually is using move_native_irq.
