From 27bf71c2a7e596ed34e9bf2d4a5030321a09a1ad Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 25 Sep 2006 23:31:15 -0700 Subject: [PATCH] [PATCH] reduce MAX_NR_ZONES: remove display of counters for unconfigured zones eventcounters: Do not display counters for zones that are not available on an arch Do not define or display counters for the DMA32 and the HIGHMEM zone if such zones were not configured.
