From: Mike Travis Date: Wed, 17 Dec 2008 01:33:55 +0000 (-0800) Subject: x86: update add-cpu_mask_to_apicid_and to use struct cpumask* X-Git-Tag: v2.6.29-rc1~538^2~21^2~11 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=6eeb7c5a99434596c5953a95baa17d2f085664e3;p=linux-2.6-omap-h63xx.git x86: update add-cpu_mask_to_apicid_and to use struct cpumask* Impact: use updated APIs Various API updates for x86:add-cpu_mask_to_apicid_and (Note: separate because previous patch has been "backported" to 2.6.27.)
