    IRQ: manually EOI migrating line interrupts
    
    When migrating IO-APIC line level interrupts between PCPUs, the
    migration code rewrites the IO-APIC entry to point to the new
    CPU/Vector before EOI'ing it.
    
    The EOI process says that EOI'ing the Local APIC will cause a
    broadcast with the vector number, which the IO-APIC must listen to to
    clear the IRR and Status bits.
    
    In the case of migrating, the IO-APIC has already been
    reprogrammed so the EOI broadcast with the old vector fails to match
    the new vector, leaving the IO-APIC with an outstanding vector,
    preventing any more use of that line interrupt.  This causes a lockup
    especially when your root device is using PCI INTA (megaraid_sas
    driver *ehem*)
    
    However, the problem is mostly hidden because send_cleanup_vector()
    causes a cleanup of all moving vectors on the current PCPU in such a
    way which does not cause the problem, and if the problem has occured,
    the writes it makes to the IO-APIC clears the IRR and Status bits
    which unlocks the problem.
    
    This fix is distinctly a temporary hack, waiting on a cleanup of the
    irq code.  It checks for the edge case where we have moved the irq,
    and manually EOI's the old vector with the IO-APIC which correctly
    clears the IRR and Status bits.  Also, it protects the code which
    updates irq_cfg by disabling interrupts.
