[PATCH 1/6] cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): x86

From: Rusty Russell
Date: Sun Dec 07 2008 - 06:01:34 EST

(The actual patch will go via git with all the other x86 cpumask patches,
this is just posted here for completeness).

The old topology_core_siblings() and topology_thread_siblings() return
a cpumask_t; these new ones return a (const) struct cpumask *.
