The patches have been pushed to hyperv-next. Roman and Nuno, please
check the tree for correctness.

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.

Thanks,
Wei.
