The patch titled

has been removed from the -mm tree. Its filename was
mm-page_owner-constify-dump_page_owner.patch

------------------------------------------------------
From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
Subject: mm/page_owner: constify dump_page_owner
dump_page_owner() only uses struct page to find the page_ext, and
lookup_page_ext() already takes a const argument.
