From ef58978f1eaab140081ec1808d96ee06e933e760 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Fri, 15 Jan 2016 16:54:57 -0800 Subject: mm: define MADV_FREE for some arches Most architectures use asm-generic, but alpha, mips, parisc, xtensa need their own definitions. This patch defines MADV_FREE for them so it should fix build break for their architectures. Maybe, I should split and feed pieces to arch maintainers but included here for mmotm convenience.

At present, '8' can be shared with all architectures, so redefine it to '8'.
