Subject: [PATCH v3 03/16] Introduce stub routine cpu_desc_avail
Date: Mon,  2 Mar 2015 13:43:55 +0100	[thread overview]
Message-ID: <1425300248-40277-4-git-send-email-mimu@linux.vnet.ibm.com> (raw)
In-Reply-To: <1425300248-40277-1-git-send-email-mimu@linux.vnet.ibm.com>

This patch introduces the function cpu_desc_avail() which returns by
default true if not architecture specific implemented. Its intention
is to indicate if the cpu model description is available for display
by list_cpus(). This change allows cpu model descriptions to become
dynamically created by evaluating the runtime context instead of
putting static cpu model information at display.
