Michal Hocko c02e50bb8a mm, page_alloc: do not report all nodes in show_mem
Patch series "show_mem updates", v2.

This is a mixture of one bug fix (patch 1), an enhancement (patch 2) and
cleanups (the rest of the series).  First two patches should be really
straightforward.  Patch 3 removes some arch specific show_mem
implementations because I think they are quite outdated and do not
really serve any useful purpose anymore.  I think we should really
strive to have a consistent show_mem output regardless of the
architecture.  If some architecture is really special and wants to dump
something additional we should do that via an arch specific hook.

The last patch adds nodemask parameter so that we do not rely on the
hardcoded mems_allowed of the current task when doing the node
filtering.  I consider this more a cleanup than a fix because basically
all users use a nodemask which is a subset of mems_allowed.  There is
only one call path in the memory hotplug which doesn't comply with this
but that is hardly something to worry about.

This patch (of 4):

Commit 599d0c954f ("mm, vmscan: move LRU lists to node") has added per
numa node statistics to show_mem but it forgot to add
skip_free_areas_node to filter out nodes which are outside of the
allocating task numa policy.  Add this check to not pollute the output
with the pointless information.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
