- * These structs MUST NOT be changed.
- * They are the ABI between hypervisor and guest OS.
- * Both Xen and KVM are using this.
- *
- * pvclock_vcpu_time_info holds the system time and the tsc timestamp
- * of the last update. So the guest can use the tsc delta to get a
- * more precise system time.  There is one per virtual cpu.
- *
- * pvclock_wall_clock references the point in time when the system
- * time was zero (usually boot time), thus the guest calculates the
- * current wall clock by adding the system time.
- *
- * Protocol for the "version" fields is: hypervisor raises it (making
- * it uneven) before it starts updating the fields and raises it again
- * (making it even) when it is done.  Thus the guest can make sure the
- * time values it got are consistent by checking the version before
- * and after reading them.
