[merged mm-stable] mm-khugepaged-introduce-khugepaged_enter_vma-helper.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: khugepaged: introduce khugepaged_enter_vma() helper
has been removed from the -mm tree.  Its filename was
     mm-khugepaged-introduce-khugepaged_enter_vma-helper.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

From: Yang Shi <shy828301@gmail.com>
Subject: mm: khugepaged: introduce khugepaged_enter_vma() helper

The khugepaged_enter_vma_merge() actually does as the same thing as the
khugepaged_enter() section called by shmem_mmap(), so consolidate them
into one helper and rename it to khugepaged_enter_vma().
