Subject: [PATCH] x86_32: remove warning message not used
Date: Mon, 14 Jan 2008 11:04:06 -0800 [thread overview]
Message-ID: <478BB226.6090105@ct.jp.nec.com> (raw)
From: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com>
smp_num_siblings hasn't been updated at this point yet, so it's always 1.
This polling and HT warning message is never shown.
