[merged] mm-vmstat-skip-reporting-offline-pages-in-pagetypeinfo.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm, vmstat: skip reporting offline pages in pagetypeinfo
has been removed from the -mm tree.  Its filename was
     mm-vmstat-skip-reporting-offline-pages-in-pagetypeinfo.patch

This patch was dropped because it was merged into mainline or a subsystem tree

From: Michal Hocko <mhocko@suse.com>
Subject: mm, vmstat: skip reporting offline pages in pagetypeinfo

pagetypeinfo_showblockcount_print skips over invalid pfns but it would
report pages which are offline because those have a valid pfn.  Their
migrate type is misleading at best.  Now that we have pfn_to_online_page()
we can use it instead of pfn_valid() and fix this.
