Subject: [PATCH 05/16] x86: update add-cpu_mask_to_apicid_and to use struct cpumask*
Date: Mon, 15 Dec 2008 18:24:14 -0800 [thread overview]
Message-ID: <20081216022410.530062000@polaris-admin.engr.sgi.com> (raw)
In-Reply-To: <20081216022409.679598000@polaris-admin.engr.sgi.com>
[-- Attachment #1: 0005-x86-update-add-cpu_mask_to_apicid_and-to-use-struct.patch --]
[-- Type: text/plain, Size: 13417 bytes --]
Impact: use updated APIs
