811553 - Only count major page faults when possible

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Attachment: patch

Windows is only able to tell us how many total page faults there have been. Linux and Mac can separate major faults from minor faults. Originally, I wanted to be consistent across platforms, so I only collected the total. However, the total isn't very useful, and most of the data I look at comes from Linux or Mac, so we might as well be collecting the right number.
