From: Chen Gang <gang.chen.5i5j@xxxxxxxxx>
Subject: arch/*/include/uapi/asm/mman.h: : let MADV_FREE have same value for all architectures
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'.
