I'm now deeply confused.

Two days ago I merged a version which you sent me.  It is presently at
http://ozlabs.org/~akpm/mmotm/broken-out/debugging-keep-track-of-page-owners.patch.

Today you sent a new version.  My earlier email showed the difference
between these two versions.

AFACIT that difference was undescribed.  I can see that the new version
uses the stack-tracing infrastructure, but the change to
pagetypeinfo_showmixedcount_print() is a mystery.
