Instead of marking the NUMA_MIGRATE_IRQ_DESC config option broken, I
would like to see it removed in 2.6.30 (i.e., apply the first patch in
this patchset for 2.6.30). As this simplifies quite a bit of code, this
will help anyone debugging a problem in this irq handling area, during
the life span of any distro carrying this kernel version.

thanks,
