From f06a96844a577c43249fce25809a4fae07407f46 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 25 Sep 2006 23:31:10 -0700 Subject: [PATCH] reduce MAX_NR_ZONES: fix MAX_NR_ZONES array initializations Fix array initialization in lots of arches The number of zones may now be reduced from 4 to 2 for many arches. Fix the array initialization for the zones array for all architectures so that it is not initializing a fixed number of elements.

Currently we use a difficult to read sequence of pointer dereferencing. Put that into an inline function and use throughout VM. Maybe we can find a way to optimize the lookup in the future.
