Hello dietlibc members: When I sent a Linux kernel patch for uapi, some members suggest me to Cc dietlibc members, so I forward the related mail to dietlibc mailing list. Please check, and welcome any ideas, suggestions, or completions. Thanks. -------- Forwarded Message -------- 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 From: Chen Gang <gang.chen.5i5j@xxxxxxxxx> To: akpm@xxxxxxxxxxxxxxxxxxxx <akpm@xxxxxxxxxxxxxxxxxxxx>, rth@xxxxxxxxxxx <rth@xxxxxxxxxxx>, ink@xxxxxxxxxxxxxxxxxxxx <ink@xxxxxxxxxxxxxxxxxxxx>, mattst88@xxxxxxxxx <mattst88@xxxxxxxxx>, Ralf Baechle <ralf@xxxxxxxxxxxxxx>, jejb@xxxxxxxxxxxxxxxx <jejb@xxxxxxxxxxxxxxxx>, deller@xxxxxx <deller@xxxxxx>, chris@xxxxxxxxxx <chris@xxxxxxxxxx>, jcmvbkbc@xxxxxxxxx <jcmvbkbc@xxxxxxxxx>, Arnd Bergmann <arnd@xxxxxxxx>, minchan@xxxxxxxxxx CC: linux-kernel@xxxxxxxxxxxxxxx <linux-kernel@xxxxxxxxxxxxxxx>, linux-arch@xxxxxxxxxxxxxxx, linux-api@xxxxxxxxxxxxxxx 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'.
