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'.
Recently, I cleaned MADV_FREE patchset up and will send uptodate version to Andrew to replace old implementation in mmotm tree which is not a linus's tree so this change shouldn't break anyting. When I look at status of this patch, it seems Andrew missed it so I want to include this patch when I respin if you don't mind. Is it okay for you? Thanks.
