[PATCH 3.14 67/77] mm: make copy_pte_range static again

[Greg Kroah-Hartman]

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

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

From: Jerome Marchand <jmarchan@xxxxxxxxxx>

commit 21bda264f4243f61dfcc485174055f12ad0530b4 upstream.

Commit 71e3aac0724f ("thp: transparent hugepage core") adds
copy_pte_range prototype to huge_mm.h.  I'm not sure why (or if) this
function have been used outside of memory.c, but it currently isn't.
This patch makes copy_pte_range() static again.
