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

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

[ Upstream commit 812264550dcba6cdbe84bfac2f27e7d23b5b8733 ]

page.h uses '_AC' in the definition of PAGE_SIZE, but doesn't include
linux/const.h where this is defined. This produces build warnings when only
asm/page.h is included by asm code.
