Hi,
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implementations because I think they are quite outdated and do not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 might be missing something
which is why this patch is RFC. 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.
Thoughts, comments?

mm, page_alloc: do not report all nodes in show_mem
mm, page_alloc: warn_alloc print nodemask
arch, mm: remove arch specific show_mem
lib/show_mem.c: teach show_mem to work with the given nodemask
