This isn't really Xen time code, but unchanged Linux time code. I don't know
which tree you quoted the code from -- 2.6.18 has similar but not identical.
Anyway, I suggest try using the jiffy-comparison macros from
<linux/jiffies.h>: time_before(), time_after(), etc. These are designed to
work even when jiffies wraps. Feel free to send patch(es) for that, if you
test that out and it works okay.
