From 9501b2efd70ad3957a70d44de54dab7c52f9b882 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Sat, 9 Feb 2008 23:24:08 +0100 Subject: [PATCH] x86: GEODE: MFGPT: replace 'flags' field with 'avail' bit Drop F_AVAIL and the 'flags' field, replacing with an 'avail' bit. This looks more understandable to me.
