-    powerpc/mpic: Fix mapping of "DCR" based MPIC variants
-    
-    Commit 31207dab7d2e63795eb15823947bd2f7025b08e2
-    "Fix incorrect allocation of interrupt rev-map"
-    introduced a regression crashing on boot on machines using
-    a "DCR" based MPIC, such as the Cell blades.
-    
-    The reason is that the irq host data structure is initialized
-    much later as a result of that patch, causing our calls to
-    mpic_map() do be done before we have a host setup.
-    
-    Unfortunately, this breaks _mpic_map_dcr() which uses the
-    mpic->irqhost to get to the device node.
-    
-    This fixes it by, instead, passing the device node explicitely
-    to mpic_map().
