The patch titled
pagemap: return map count, not reference count, in /proc/kpagecount
has been removed from the -mm tree. Its filename was
pagemap-return-map-count-not-reference-count-in-proc-kpagecount-v2-of-series.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: pagemap: return map count, not reference count, in /proc/kpagecount
From: "Thomas Tuttle" <ttuttle@xxxxxxxxxx>
Since pagemap is all about examining pages mapped into processes' memory
spaces, it makes sense for kpagecount to return the map counts, not the
reference counts.
