Subject: [PATCH v5 03/12] arch: uapi: asm: mman.h: Let MADV_FREE have same value for all architectures

From: Chen Gang <gang.chen.5i5j@...il.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'.
