I see you dropped jiffies_hi update in timer int.
IMHO argument on wasting 6 CPU cycles or so per each timer int:
+ if(++jiffies==0) jiffies_hi++;
is not justified. I'd rather see simple and correct code in timer int
rather than jumping thru the hoops in get_jiffies_64().
For CPU cycle saving zealots: I advocate saving 2 static longs in get_jiffies
