All,
Nigel was asking about some suspend2 patches, and while looking at them
I noticed what looks to be a bug where jiffies and wall_jiffies are
modified without holding the xtime_lock in the resume path.
This patch should fix it, but I wanted to get some review and testing
done before I submit it.
thanks
