From fb8e8375394e1156a5a1e7ba53504b141d2365a8 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge <jeremy@goop.org> Date: Thu, 27 Mar 2008 17:28:39 -0700 Subject: [PATCH] x86: sparsemem: reduce i386 PAE section size A 1G section size makes memory hotplug too coarse in a virtual environment. Retuce it by a factor of 2 to 512M. I would have liked to make it smaller, but it runs out of reserved flags in the page flags.
