From 6d23f8a5d432337aa2590ea8fd5eee8b0bc28eee Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Wed, 22 Feb 2017 15:46:13 -0800 Subject: arch, mm: remove arch specific show_mem We have a generic implementation for quite some time already. If there is any arch specific information to be printed then we should add a callback called from the generic code rather than duplicate the whole show_mem. The current code has resulted in the code duplication and the output divergence which is both confusing and adds maintainance costs. Let's just get rid of this mess.
