[ 003/150] x86-32, mm: Remove reference to alloc_remap()

[Greg Kroah-Hartman]

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H. Peter Anvin" <hpa@xxxxxxxxxxxxxxx>

commit 07f4207a305c834f528d08428df4531744e25678 upstream.

We have removed the remap allocator for x86-32, and x86-64 never had
it (and doesn't need it).  Remove residual reference to it.
