Subject: [PATCH 16/16] x86: Introduce topology_core_cpumask()/topology_thread_cpumask()
Date: Mon, 15 Dec 2008 18:24:25 -0800	[thread overview]
Message-ID: <20081216022412.005499000@polaris-admin.engr.sgi.com> (raw)
In-Reply-To: <20081216022409.679598000@polaris-admin.engr.sgi.com>

[-- Attachment #1: 0020-cpumask-Introduce-topology_core_cpumask-topology_.patch --]
[-- Type: text/plain, Size: 1071 bytes --]

Impact: new API

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