- move-vmalloc_to_page-to-mm-vmalloc.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     Move vmalloc_to_page() to mm/vmalloc.
has been removed from the -mm tree.  Its filename was
     move-vmalloc_to_page-to-mm-vmalloc.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: Move vmalloc_to_page() to mm/vmalloc.
From: Christoph Lameter <clameter@sgi.com>

We already have page table manipulation for vmalloc in vmalloc.c. Move the
vmalloc_to_page() function there as well.

Move the definitions for vmalloc related functions in mm.h to a newly created
section.  A better place would be vmalloc.h but mm.h is basic and may depend
on these functions.  An alternative would be to include vmalloc.h in mm.h
(like done for vmstat.h).
