[PATCH v2 03/13] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures

From: Minchan Kim
Date: Tue Nov 03 2015 - 20:29:51 EST


From: Chen Gang <gang.chen.5i5j@xxxxxxxxx>

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'.
