[merged mm-stable] mm-delete-stale-comment-about-cachelines.patch removed from -mm tree

The quilt patch titled
     Subject: mm: delete stale comment about cachelines
has been removed from the -mm tree.  Its filename was
     mm-delete-stale-comment-about-cachelines.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

These comments have been wrong since commit a211c6550efc ("mm: page_alloc:
defrag_mode kswapd/kcompactd watermarks") added NR_FREE_PAGES_BLOCKS. 
Since nobody has complained about it in the last year, it seems unlikely
these comments were particularly useful anyway, so delete them.
