From b3f2f6cd1ff935ecac9a5346904b899d7af689fe Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 30 May 2010 10:08:03 -0700 Subject: ia64: revert __node_random addition This partially reverts commit 4ec37de89d8c758ee8115e0e64b3f994910789ee ("[IA64] Fix build breakage"), since the commit that made it necessary got reverted earlier (see commit 35926ff5fba8, 'Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"') Even if we ever re-introduce this, there is no reason to make __node_random be some architecture-specific function.
