mainline inclusion
from mainline-v5.4-rc1
commit 7ae88534
category: bugfix
bugzilla: 47240
CVE: NA

-------------------------------------------------

A later patch makes THP deferred split shrinker memcg aware, but it needs
page->mem_cgroup information in THP destructor, which is called after
mem_cgroup_uncharge() now.

So move mem_cgroup_uncharge() from __page_cache_release() to compound page
destructor, which is called by both THP and other compound pages except
HugeTLB.  And call it in __put_single_page() for single order page.
