From 2258a5bb1064351b552aceaff29393967d694fa3 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 26 Dec 2008 22:23:41 +1030 Subject: cpumask: alpha: 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. I'm not sure the existing code even compiles, but new version is straightforward.
