This

```c
union hv_arm64_pending_synthetic_exception_event {
u64 as_uint64[2];
struct {
u8 event_pending : 1;
u8 event_type : 3;
u8 reserved : 4;
u8 rsvd[3];
u64 context;
} __packed;
};
```

needs to have the `u32 exception_type;` field:

```c
union hv_arm64_pending_synthetic_exception_event {
u64 as_uint64[2];
struct {
u8 event_pending : 1;
u8 event_type : 3;
u8 reserved : 4;
u8 rsvd[3];
u32 exception_type;
u64 context;
} __packed;
};
```
as otherwise the struct won't cover the array.
Testing the VMs currently with the latest hyperv-next.
