The patch titled
Subject: mm: define MADV_FREE for some arches

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

From: Minchan Kim <minchan@xxxxxxxxxx>
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@xxxxxxxxx: let MADV_FREE have same value for all architectures]
