From: Rusty Russell Date: Sat, 13 Dec 2008 10:50:27 +0000 (+1030) Subject: cpumask: Introduce cpumask_of_{node,pcibus} to replace {node,pcibus}_to_cpumask X-Git-Tag: v2.6.29-rc1~538^2~24^2~2 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f0b848ce6fe9062d504d997e9e97fe0f87d57217;p=linux-2.6-omap-h63xx.git cpumask: 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. This defines them in the generic non-NUMA case.
