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

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

From: Steve Capper <steve.capper@linaro.org>

commit db4ed53cfe9f5a00355891a631d47dfa3fd4541f upstream.

Modify the value of PMD_SECT_PROT_NONE to match that of PTE_NONE. This
should have been in commit 3676f9ef5481 (Move PTE_PROT_NONE higher up).
