From d7a3e4959c28bccc25dd33315809ffcf40f7493e Mon Sep 17 00:00:00 2001 From: Hugh Dickins <hugh@veritas.com> Date: Sat, 13 Sep 2008 02:33:13 -0700 Subject: [PATCH] mm: ifdef Quicklists in /proc/meminfo A "Quicklists: 0 kB" line has just started appearing in /proc/meminfo, but most architectures (including x86) don't have them configured, so #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.
