This patch series modifies the ARM GICv3 ITS to use the already existing
send_msi virtual function when writing the GITS_TRANSLATER in order to be able
to modify the final DeviceID to an implementation specific version that requires
extra information besides the BDF that comes in the requester_id. This is
achieved by using inheritance and redefinition of the send_msi while the
parent's send_msi could still be used to inject the modified DeviceID.

Roque Arcudia Hernandez (2):
  hw/intc/arm_gicv3_its_common: Increase DeviceID to 32 bits
  hw/intc/arm_gicv3_its: Use send_msi in the GITS_TRANSLATER write
