With 64 bits to work with, jiffies_64 will not wrap around in a time frame that need concern most of us - at least until some future kernel starts using a gigahertz internal clock.

Actually, even with a Ghz internal clock a 64-bit counter will still need about 600 years before it ticks over. Even with a 100Ghz internal clock we will experience wrap-around only once every 6 years. Few systems stay up that long.
