Subject: [RFC PATCH 1/8] ARM: gic: Support forcing cpumask for possible cpus in the system
Date: Mon, 18 Jun 2012 13:30:04 +0200 [thread overview]
Message-ID: <1340019011-18642-2-git-send-email-monstr@monstr.eu> (raw)
In-Reply-To: <1340019011-18642-1-git-send-email-monstr@monstr.eu>
gic_set_affinity doesn't support force option. Force option
should work with all possible cpus in the system not only with
online cpus.
