The patch titled
Subject: rmap: drop support of non-linear mappings
has been removed from the -mm tree. Its filename was
rmap-drop-support-of-non-linear-mappings.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
Subject: rmap: drop support of non-linear mappings
We don't create non-linear mappings anymore. Let's drop code which
handles them in rmap.

The idea is, first at flush_dcache_page() time, if
- page->mapping->i_mmap is an empty tree and ->i_mmap_nonlinear
- an empty list, just mark the architecture private page flag bit.
- Later, in update_mmu_cache(), a check is made of this flag bit,

IMPORTANT NOTE: It is often important, if you defer the flush,
that the actual flush occurs on the same CPU

- * objrmap doesn't work for nonlinear VMAs because the assumption that

- * Consequently, given a particular page and its ->index, we cannot locate the
- * ptes which are mapping that page without an exhaustive linear search.
- *
- * So what this code does is a mini "virtual scan" of each nonlinear VMA which
- * maps the file to which the target page belongs. The ->vm_private_data field
- * holds the current cursor into that scan. Successive searches will circulate
- * around the vma's virtual address space.
- *
- * So as more replacement pressure is applied to the pages in a nonlinear VMA,
- * more scanning pressure is placed against them as well. Eventually pages
- * will become fully unmapped and are eligible for eviction.
- *
- * For very sparsely populated VMAs this is a little inefficient - chances are
- * there there won't be many ptes located within the scan cluster. In this case
- * maybe we could scan further - to the end of the pte page, perhaps.
