From e16b38f71322efd8a221f64b6ddc0748d21d2e1a Mon Sep 17 00:00:00 2001 From: Greg Banks Date: Mon, 2 Oct 2006 02:17:40 -0700 Subject: [PATCH] [PATCH] cpumask: export cpu_online_map and cpu_possible_map consistently cpumask: ensure that the cpu_online_map and cpu_possible_map bitmasks, and hence all the macros in that require them, are available to modules for all supported combinations of architecture and CONFIG_SMP.
