 * How should CPU0 event-channel notifications be delivered?

 * val[63:56] == 0: val[55:0] is a delivery GSI (Global System Interrupt).

 * val[63:56] == 1: val[55:0] is a delivery PCI INTx line, as follows:

 *                  Domain = val[47:32], Bus  = val[31:16],

 *                  DevFn  = val[15: 8], IntX = val[ 1: 0]

 * val[63:56] == 2: val[7:0] is a vector number.

 *

 * If val == 0 then CPU0 event-channel notifications are not delivered.

 * If val != 0, val[63:56] encodes the type, as follows:
