[PATCH] rmap 38 remove anonmm rmap
From: Hugh Dickins <hugh@veritas.com>
Before moving on to anon_vma rmap, remove now what's peculiar to anonmm rmap:
the anonmm handling and the mremap move cows. Temporarily reduce
page_referenced_anon and try_to_unmap_anon to stubs, so a kernel built with
this patch will not swap anonymous at all.
