I am looking at
similar in the the software dev manual).
The PublicDescription for ITLB_MISSES.WALK_COMPLETED says "Counts
completed page walks (2M and 4M page sizes) ... " while I assume this
to be for all page sizes as per the BriefDescription. It possibly
looks like a copy pasta error from ITLB_MISSES.WALK_COMPLETED_2M_4M.
Is that correct?
