[PATCH 3.16 35/63] arm64: kernel: Include _AC definition in page.h

From: Ben Hutchings
Date: Wed Jan 08 2020 - 14:46:41 EST


3.16.81-rc1 review patch. If anyone has any objections, please let me know.

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

From: James Morse <james.morse@xxxxxxx>

commit 812264550dcba6cdbe84bfac2f27e7d23b5b8733 upstream.

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.
