From fbb776c3ca4501d5a2821bf1e9bceefcaec7ae47 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 26 Dec 2008 22:23:40 +1030 Subject: cpumask: IA64: Introduce cpumask_of_{node,pcibus} to replace {node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. We can also use the new for_each_cpu_and() to avoid a temporary cpumask, and a gratuitous test in sn_topology_show.
