The patch titled
page_cgroup-reduce-allocation-overhead-for-page_cgroup-array-for-config_sparsemem-fix
has been removed from the -mm tree. Its filename was
page_cgroup-reduce-allocation-overhead-for-page_cgroup-array-for-config_sparsemem-fix.patch
This patch was dropped because it was folded into page_cgroup-reduce-allocation-overhead-for-page_cgroup-array-for-config_sparsemem.patch

Subject: page_cgroup-reduce-allocation-overhead-for-page_cgroup-array-for-config_sparsemem-fix
From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: mm: do not define unused free_page_cgroup without memory hotplug
Without memory hotplug configured in, the page cgroup array is never
actually freed again:
mm/page_cgroup.c:149:13: warning: `free_page_cgroup' defined but not used
Wrap the definition in ifdefs. Rather than moving it into an existing
ifdef section, to keep it close to its allocation counterpart.
