I think that is more due to how you added the MPIC error interrupts

and

issues w/that code.  If you are treating the MPIC error interrupts

as a

cascade than they should have a distinct linux IRQ space from the
standard MPIC interrupts.  This is how the MSIs work (as an

example).
In case of error interrupts we are depending on the mpic_host_maps
for mapping and interrupt specifier translations. There is no separate
initialization as in case of MSIs. That's the reason I am treating
error interrupts as mpic internal interrupt sources. 

It makes sense to have an allocator for MPIC vectors but it should be a
single allocator shared with the MSI code.
