cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): x86
PATCH 1/6 cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): x86
(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 *.
