Li Fei1 80c7da8f1c hv: vioapic: expose ioapic to guest unconditionally ... Some OSes assume the platform must have the IOAPIC. For example: Linux Kernel allocates IRQ force from GSI (0 if there's no PIC and IOAPIC) on x86. And it thinks IRQ 0 is an architecture special IRQ, not for device driver. As a result, the device driver may goes wrong if the allocated IRQ is 0 for RTVM. This patch expose vIOAPIC to RTVM with LAPIC passthru even though the RTVM can't use IOAPIC, it servers as a place holder to fullfil the guest assumption. After vIOAPIC has exposed to guest unconditionally, the 'ready' field could be removed since we do vIOAPIC initialization for each guest.
