From de2d9445f1627830ed2ebd00ee9d851986c940b5 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Jan 2011 14:37:41 +0100 Subject: x86: Unify node_to_cpumask_map handling between 32 and 64bit x86_32 has been managing node_to_cpumask_map explicitly from map_cpu_to_node() and friends in a rather ugly way. With previous changes, it's now possible to share the code with 64bit. * When CONFIG_NUMA_EMU is disabled, numa_add/remove_cpu() are implemented in numa.c and shared by 32 and 64bit. CONFIG_NUMA_EMU versions still live in numa_64.c. NUMA_EMU's dependency on 64bit is planned to be removed and the above should go away together. * identify_cpu() now calls numa_add_cpu() for 32bit too. This makes the explicit mask management from map_cpu_to_node() unnecessary. * The whole x86_32 specific map_cpu_to_node() chunk is no longer necessary. Dropped.
