Subject: [PATCH 31/34] thermal: cpu cooling: use const parameter while registering
Date: Sun, 2 Dec 2012 22:45:05 +0800 [thread overview]
Message-ID: <1354459508-3707-31-git-send-email-rui.zhang@intel.com> (raw)
In-Reply-To: <1354459508-3707-1-git-send-email-rui.zhang@intel.com>
From: Eduardo Valentin <eduardo.valentin@ti.com>
There are predefined cpu_masks that are const data structures.
This patch changes the cpu cooling register function so that
those const cpu_masks can be used, without compilation warnings.
include/linux/cpumask.h
* The following particular system cpumasks and operations manage
* possible, present, active and online cpus.
*
* cpu_possible_mask- has bit 'cpu' set iff cpu is populatable
* cpu_present_mask - has bit 'cpu' set iff cpu is populated
* cpu_online_mask - has bit 'cpu' set iff cpu available to scheduler
* cpu_active_mask - has bit 'cpu' set iff cpu available to migration
*
