The packet scheduler simulates 64 bit jiffies on 32 bit platforms by running
a timer keeping a mark and and offset.  Since there is no locking and this is
racy and doesn't handle jiffie wrap real well.

We can use get_jiffies_64 on 2.6 do get what is needed.
The downside is the overhead of a function call, and a cache miss in
get_jiffies_64.
