[PATCH] mm: ifdef Quicklists in /proc/meminfo

From: Hugh Dickins
Date: Mon Sep 08 2008 - 08:58:24 EST


A "Quicklists: 0 kB" line has just started appearing in
/proc/meminfo, but most architectures (including x86) don't have
them configured: may we please #ifdef it, like the highmem lines?

And those architectures which do have quicklists configured are
using them for page tables: so let's place it next to PageTables.
