Subject: [Patch] x86: export cpu_llc_id for edac drivers
Date: Tue, 15 Sep 2009 04:17:34 -0400 [thread overview]
Message-ID: <20090915082005.4701.86110.sendpatchset@localhost.localdomain> (raw)
When I compiled today's Linus tree, I got a link error from
drivers/edac/edac_mce_amd.c:408, it complained about not finding
symbol 'per_cpu__cpu_llc_id'. This is due to we don't export
'cpu_llc_id'.
This patch fixes it.
