I just double-checked whether it was due to some configuration change
that I made, but it wasn't.  Just running 'yes "" | make oldconfig'
produced a configuration that builds with 2.6.35.2.

Anyway, including <linux/jiffies.h> seems to be a reasonable precaution
measure to me, but I'm just a layman.
