There are two parts:
- Unconditionally zero the output area. The length of the incoming
vector has been seen from 1 to 4 bytes, even though just the first
byte might need to be handled. But also, this ensures any possibly
unhandled offset will return zeroed result to the caller. The former
implementation used an I/O port which seems to behave differently from
MMIO and wouldn't require explicit output zeroing.
- An access with zero offset still takes place and needs to be handled.
Fixes#2437.

The following is from the Hyper-V specification v6.0b.
Cpuid leaf 0x40000003 EDX:
Bit 3: Support for physical CPU dynamic partitioning events is
available.
When Windows determines to be running under a hypervisor, it will
require this cpuid bit to be set to support dynamic CPU operations.
Cpuid leaf 0x40000004 EAX:
Bit 5: Recommend using relaxed timing for this partition. If
used, the VM should disable any watchdog timeouts that
rely on the timely delivery of external interrupts.
This bit has been figured out as required after seeing guest BSOD
when CPU hotplug bit is enabled. Race conditions seem to arise after a
hotplug operation, when a system watchdog has expired.
Closes#1799.

On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.
Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.
The setting of X86 IRQ routing entries are not impacted.
