[PATCH] Avoid calling get_irq_server() with a real, not virtual irq.

[Michal Ostrowski]

If you set the priority level to 0xff, you've disabled the interrupt:
the XICS model prohibits it from being delivered.  


On the other hand, calling get_irq_server() is obviously wrong.
xics_remap_irq() calls xics_mask_real_irq() in the case that it was not
able to convert real->virt.  That being the case, how can we expect
xics_mask_real_irq to be able to do so in order to call
get_irq_server()?
