Subject: [PATCH v3 03/17] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
Date: Thu, 12 Nov 2015 13:32:59 +0900	[thread overview]
Message-ID: <1447302793-5376-4-git-send-email-minchan@kernel.org> (raw)
In-Reply-To: <1447302793-5376-1-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'.
