From b9b15780f808efa2c897f337644ba7a2bec03ecc Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 25 Sep 2006 23:31:16 -0700 Subject: [PATCH] [PATCH] reduce MAX_NR_ZONES: fix i386 SRAT check for MAX_NR_ZONES We cannot check MAX_NR_ZONES since it not defined in the preprocessor anymore. So remove the check. The maximum number of zones per node for i386 is 3 since i386 does not support ZONE_DMA32.
