Subject: [PATCH] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures
Date: Fri, 05 Dec 2014 06:58:29 +0800 [thread overview]
Message-ID: <5480E715.3020900@gmail.com> (raw)
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'.
