+ * GICv3 distributor and redistributor emulation

+ * GICv3 emulation is currently only supported on a GICv3 host (because
+ * we rely on the hardware's CPU interface virtualization support), but
+ * supports both hardware with or without the optional GICv2 backwards
+ * compatibility features.
+ *
+ * Limitations of the emulation:
+ * (RAZ/WI: read as zero, write ignore, RAO/WI: read as one, write ignore)
+ * - We do not support LPIs (yet). TYPER.LPIS is reported as 0 and is RAZ/WI.
+ * - We do not support the message based interrupts (MBIs) triggered by
+ *   writes to the GICD_{SET,CLR}SPI_* registers. TYPER.MBIS is reported as 0.
+ * - We do not support the (optional) backwards compatibility feature.
+ *   GICD_CTLR.ARE resets to 1 and is RAO/WI. If the _host_ GIC supports
+ *   the compatiblity feature, you can use a GICv2 in the guest, though.
+ * - We only support a single security state. GICD_CTLR.DS is 1 and is RAO/WI.
+ * - Priorities are not emulated (same as the GICv2 emulation). Linux
+ *   as a guest is fine with this, because it does not use priorities.
+ * - We only support Group1 interrupts. Again Linux uses only those.
