Subject: [PATCH v5 03/12] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
Date: Mon, 30 Nov 2015 15:39:34 +0900 [thread overview]
Message-ID: <1448865583-2446-4-git-send-email-minchan@kernel.org> (raw)
In-Reply-To: <1448865583-2446-1-git-send-email-minchan@kernel.org>
From: Chen Gang <gang.chen.5i5j@gmail.com>
For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.
At present, '8' can be shared with all architectures, so redefine it to
'8'.
