Subject: [PATCH 1/6] cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): x86
Date: Sun, 7 Dec 2008 21:31:17 +1030 [thread overview]
Message-ID: <200812072131.18087.rusty@rustcorp.com.au> (raw)
(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 *.
