irq: x86_64_dump_irq: irq_desc[] does not exist?
Is that because of the irq data structures changed in kernel from static
to dynamic allocated?
It looks like that, starting in 2.6.29, the irq_desc[] array can be replaced by
an irq_desc_ptrs[] array if the kernel is configured with CONFIG_SPARSE_IRQ.
I'm fixing the "kmem -z" as we speak -- I'll look into this afterwards.
