[merged] mm-define-madv_free-for-some-arches.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm: define MADV_FREE for some arches
has been removed from the -mm tree.  Its filename was
     mm-define-madv_free-for-some-arches.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Minchan Kim <minchan@kernel.org>
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.

[gang.chen.5i5j@gmail.com: let MADV_FREE have same value for all architectures]
