-/**
- * gettimeoffset - number of nsecs elapsed since &xtime was last updated
- *
- * This function is used by do_gettimeofday() to determine the number
- * of nsecs that have elapsed since the last update to &xtime.  On SN
- * this is accomplished using the RTC built in to each Hub chip; each
- * is guaranteed to be synchronized by the PROM, so a local read will
- * suffice (GET_RTC_COUNTER() does this for us).  A snapshot of the RTC
- * value is taken every time wall_jiffies is updated by the
- * update_wall_time_hook (sn2_update_wall_time) which means we don't
- * have to adjust for lost jiffies ticks or anything like that.
